<br />
* Invited - Hovanes Egiyan, Stephanie Worthington, Keith Harding, Pavel Degtiarenko, Tim Whitlatch, Eugene Chudakov, Josh Ballard<br />
<br />
== Agenda ==<br />
<br />
* Review minutes from last meeting https://halldweb.jlab.org/wiki/index.php/February_27,_2024_KLONG_CPS_Design_Meeting<br />
* Review new basic 3D model and compare to Pavel's model (Pavel, Keith)<br />
** Copper Absorber updated [[media:Copper absorber.pdf]]<br />
** Tagger Hall Layout (Stephanie/Keith)<br />
* De-gaussing of Tagger magnet (all)<br />

<br />
== Minutes ==<br />
* Reviewed minutes from last meeting<br />
* Discussed progress on 3D model<br />
** Discussed possibility of removing borated poly layer from the back side when moving CPS out of beamline<br />
*** Pavel will check radiation levels<br />
*** It will make more clearance for GlueX reinstall<br />
*** Poly can be attached outside of support frame<br />
** current model shows using cartridges from the FCAL for support and alignment set at 33% in Z. Need to move them out slightly<br />
** Ok to have a gap upstream of copper absorber for water lines - total shielding thickness still needed<br />
** On downstream end, keep center Cu/W inner block up against the absorber (inside of the water lines) OK for gap outside this<br />
** Currently the copper absorber model is 1.67 cm below beam center, we will move to 2 cm below<br />
** Cu absorber water channels modified to .5 in holes x8. Keith/Josh will get Pavel a usable 3D model of the modified absorber to import into Fluka<br />
* Need to set the center of the magnet poles 2cm below beamline<br />
* Magnet pole gap is clear of all materials, Cu/W can fill in coil regions<br />

__TOC__<br />
<br />
Welcome! Have you ever wanted to edit code for GlueX analysis using smart code completion, debuggers, integrated Git, syntax highlighting, and so much more, all wrapped into one? Well look no further than Visual Studio (VS) Code! By the end of this guide, you will be able to connect to the ifarm and have all these powerful tools right at your fingertips. This includes the Extensions marketplace, which adds incredibly useful features and tools to your programming setup. If you run into any problems then please message me, Kevin Scheuer, over Slack ([mailto:kscheuer@jlab.org or email]) and let me know!<br />
<br />
<span style="color:blue">'''Windows Users:'''</span> This guide is primarily aimed at macOS / Linux users, but there will be slight deviations for windows machines. Look for <span style="color:blue">blue text</span> that will denote Windows-specific instructions.<br />
<br />
<br />
= Setup = <br />
Before beginning, please ensure you have the following:<br />
* A working JLab Computing account<br />
* A 2 Factor Authentication Method (2FA) setup. This is MobilePASS or Google Authenticator.<br />
** See the guide under '''Software''' on the [https://halldweb.jlab.org/wiki/index.php/Getting_Started_At_GlueX#Software Getting Started at GlueX page]<br />
** Or see the '''Prerequisites''' section in this [https://jlab.servicenowservices.com/kb?id=kb_article_view&sysparm_article=KB0015066 servicenow article]<br />
* Downloaded [https://code.visualstudio.com/download VS Code] for your OS<br />
<br />
== The .ssh/config file ==<br />
# Your first step for getting onto the ifarm will be creating an ssh config file, which dictates how your device, or “local machine”, will connect to the remote JLab server<br />
# Open VS Code and navigate to the '''Extensions''' tab on the left-hand sidebar. Copy and paste <code>ms-vscode-remote.remote-ssh</code> into the search bar, and install the package.<br />
#* If you can’t see the sidebar, try in the menu '''View > Appearance > Primary Side Bar'''<br />
# In the menu bar go to '''View > Command Palette'''. Search and select <code>Remote-SSH: Open SSH Configuration File</code><br />
# Your default file is likely at <code>/Users/YOUR_USERNAME/.ssh/config</code>. Select this file and it should now open in the editor view.<br />
#* If the file is not yet created, no worries. Open VS Code's integrated terminal with '''Terminal > New Terminal''' or '''View > Terminal''' and navigate to the <code>.ssh</code> folder. Run <code>touch config</code> to create a blank file. Now open the file as instructed.<br />
#* <span style="color:blue">Windows Users:</span> Your file path should be <code>C:/Users/YOUR_USERNAME/.ssh/config</code><br />
# If settings already exist in this file they can be kept, so long as they are not ifarm related. We will be using a slightly modified version from the [https://jlab.servicenowservices.com/scicomp/?id=kb_article&sysparm_article=KB0014918 JLab recommended] config file. Download the OS specific [https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=6428 custom config file] and copy/paste its contents into the .ssh/config file open in the VS Code editor<br />
# At the very bottom edit <code>User YOUR_USERNAME_HERE</code> and replace with your JLab CUE username<br />
# Notice there is now a dot next to the file name. This indicates edits have been made and need to be saved. Save the changes with '''File > Save''' and close the file by pressing the '''X''' next to the file name<br />
# Open the command palette again and search/select <code>Preferences: Open User Settings</code><br />
# Search <code>Remote.SSH: Remote Server Listen on Socket</code> and ensure this option is selected. <br />
# While we’re here, let's also change the default <code>.vscode-server</code> location. This dictates where your Extensions and some other modules will be stored, but can quickly outgrow the limits of its default location on the ifarm at <code>/home/YOUR_USERNAME/</code>. It's highly recommended to put this in a more spacious location, like a user’s directory on the work disk. Search <code>Remote.SSH: Server Install Path</code> in your user settings, and set '''key''' to <code>ifarm</code> and '''Value''' to be your directory of choice, then click '''Add item''' to save your change<br />
#* For example, my path is <code>/w/halld-scshelf2101/kscheuer/</code><br />
# Lastly, ssh needs a specific directory to be setup to work properly. Open a terminal and navigate to <code>/Users/YOUR_USERNAME/.ssh/</code> (or wherever your config file is) and perform <code>mkdir cm</code><br />
<br />
== Connecting ==<br />
# Before we go about connecting with VS Code, let's test the config file and ensure the connection can be established. Open a terminal via '''Terminal > New Terminal''' or '''View > Terminal''' and simply run <code>ssh ifarm</code>. Note that even though the terminal is "integrated" as part of VS Code, for the most part, it functions just like any terminal window<br />
# You should be prompted to enter a password, which will be your 2FA method (MobilePASS or Google Authenticator). Click enter and another prompt will appear. This time enter your JLab CUE password.<br />
# You should be taken to your home directory on an ifarm node. We now know the connection can be made. Type <code>exit</code> and click <i>enter</i> to close the session<br />
#* If you get to the JLab CUE prompt and enter your password but the connection is hanging, it may be that the ifarm node it's routing you to is having issues. There are 3 nodes 1801, 1802, and 1901. Retry from step 1 but do <code>ssh ifarmXXXX</code> replacing the X’s with one of the three node numbers<br />
# From the Command Palette run <code>Remote-SSH: Connect to Host</code>. Select the option '''ifarm'''<br />
#* If you’d prefer a new window to not be opened, execute <code>Remote-SHH: Connect Current Window to Host</code><br />
# It may ask what type of system this is, select '''Linux'''. Similar to the connection we did in the terminal, you will be prompted for 2 consecutive passcode inputs. The first will be the 2FA method, and the second your CUE password<br />
#* A popup may appear saying "The remote host may not meet VS Code Server's prerequisites for glibc and libstdc++". Essentially, support for the ifarm's current operating system will drop by January 2025, but we will be updated by then so there's no need to worry about this. A banner might also appear stating "You are connected to an OS version that is unsupported by Visual Studio Code". This too can be ignored.<br />
# VS Code will configure the connection, and if successful there should be a green status bar in the lower left corner. You can even open a terminal and see what node you are on, and verify that you are in your home directory<br />
# Congratulations, you are now connected and ready to code! You can exit at any time by clicking on that green status bar and selecting '''Close Remote Connection'''.<br />
<br />
=== Using ssh keys ===<br />
This section is completely optional, but if working correctly it means you'll never have to enter your CUE password again! In short, we'll make 2 ssh keys: one that sits on our local machine, and the "public" key that we'll place on the ifarm. There are different algorithms and key sizes you can use, here we'll be using ecdsa. <br />
<br />
# Navigate to the directory of your <code>config</code> file and run <code>ssh keygen -t ecdsa</code><br />
# It then asks for an optional passphrase for the keys. To leave it empty, just press <i>enter</i><br />
#* Note: using a non-empty passphrase has yet to be tested<br />
# Now we can copy the public key to the ifarm. Run <code>ssh-copy-id -i YOUR_KEY_NAME.pub ifarm</code> replacing <code>YOUR_KEY_NAME</code> with the key name that was generated<br />
# Enter the requested passwords. If no errors occur, then both terminal and VS Code connection methods should recognize these keys and no longer require a CUE password to be entered!<br />
<br />
== Troubleshooting ==<br />
* <i>I was able to connect before, but now it's failing and/or repeatedly asks for the password prompt</i><br />
*# To verify this is an issue with just VS Code, check that you can connect normally by running <code>ssh ifarm</code> in a terminal<br />
*# If that works, then in the command palette perform “Remote SSH: Kill VS Code Server on Host” and select ifarm. Doing this once should reset the connection<br />
*#* This shouldn't remove your extensions, but if you want to be safe you can make a backup of your <code>.vscode-server</code> on the ifarm<br />
<br />
* <i>In step 4 of '''Connecting''' I don't see an option for ifarm</i><br />
*# Set the absolute path to your custom config file by opening <code>Preferences: Open User Settings</code> in the command palette and searching for <code>Remote.SSH: Config File</code><br />
<br />
= Working With VS Code =<br />
<br />
A full tutorial on <i>how</i> to use VS Code is beyond the extent (and reasonable length) of this guide, but the [https://code.visualstudio.com/docs/introvideos/basics official getting started webpage] for VS Code is highly recommended. <br />
<br />
== Extensions ==<br />
A lot of the power of VS Code comes from its “Extensions”. Below are listed some necessary ones that allow VS Code to interact with C++ or Python nicely, but also some incredibly useful ones and highlights of their features. You can search for each extension by name, or copy-paste its ID into the search bar. Note that extensions are stored in the <code>.vscode-server</code> on the ifarm, and in <code>.vscode</code> on your local machine, and so you can have different extensions for each location. <br />

* LMS installation was on hold during beam test, but have installed 1132 fibers as of meeting<br />
** Will resume in April<br />
* Discussed asking for money to build TOF veto counter for inner region not covered by existing TOF scintillators<br />
** Narrow scintillator bars with wavelength shifting fibers + SiPM readout ?<br />
** Use discriminators + TDCs instead of flashADCs to cut down cost of electronics<br />
* Discussed idea to measure shower profile in transition region between lead tunstate and lead glass blocks<br />
** Pair spectrometer setup in hall<br />
** Have 5x5 ECAL-style modules + many FCAL lead glass blocks<br />

# Announcements<br />
# Action Items<br />
# Calibrations<br />
#*TOF: Full calibration complete. Tested one run, looks very good, resolution below 100ps (for mean-time). CCDB has been updated.<br />
#*FCAL: Calibration complete.<br />
#*BCAL: Finished. Running checks now.<br />
#*CDC: calibration is done. Naomi is doing some cross checks. Naomi refined the gains based on monitoring version 10, the plots are at [https://halldweb.jlab.org/wiki-private/index.php/CDC_calibration_status#CPP_monitoring_v10 calibration status based on ver10]. <br />
#*FDC: Keigo, done.<br />
#*CTOF, FMWPC:<br />
#** Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.<br>[https://userweb.jlab.org/~ilarin/cpp/3333/ plots made for the entire group], file name legend: 1st number - MWPC#, 2nd - 24 wires group #, 3rd - one for 1...2 hits in the group, five for 10 or more hits<br />
#* Tagger-Mic, PS, TPOL: ?<br />
#** ver10: mic. and hod. timining mostly ok., needs some tweaking of individual channels. PS timing itself looks ok however the relative timing between PS and tagger is off by 4ns(always), this inhibits to do and accidental scaling factor calibration. One block of 5 microscope columns are off regarding energy calibration, it seems the ordering is switched (this seems to be also true for the 80k run period and the 110k run period).<br />
#** ver11: looks worse regarding timing, e.g. tagger time minus RF time is off by 4ns most of the time., tagger time minus PS time is still off by 4ns<br />
#** tagger microscope walk correction does not work well for all run periods after fall 2021. Ellie Prather from UCON is working on this issue.<br />
#** Accidental Scaling Factor calibration requires Tagger and PS calibration.<br />
#** Energy calibration of tagger microscope is ok, the issue is in some "cable swap" that was not yet addressed on the translation table see: [https://logbooks.jlab.org/entry/4156839 logbook]<br />

# Previous CPP meeting: [[Π_polarizability_Meeting_Mar_6,_2024|Mar 6, 2024]]<br />
# Announcements<br />
# Action Items<br />
# Calibrations<br />
#*TOF: Full calibration complete. Tested one run, looks very good, resolution below 100ps (for mean-time). CCDB has been updated.<br />
#*FCAL: Calibration complete.<br />
#*BCAL: Finished. Running checks now.<br />
#*CDC: calibration is done. Naomi is doing some cross checks. Naomi refined the gains based on monitoring version 10, the plots are at [https://halldweb.jlab.org/wiki-private/index.php/CDC_calibration_status#CPP_monitoring_v10 calibration status based on ver10]. <br />
#*FDC: Keigo, done.<br />
#*CTOF, FMWPC:<br />
#** Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.<br>[https://userweb.jlab.org/~ilarin/cpp/3333/ plots made for the entire group], file name legend: 1st number - MWPC#, 2nd - 24 wires group #, 3rd - one for 1...2 hits in the group, five for 10 or more hits<br />
#* Tagger-Mic, PS, TPOL: ?<br />
#** ver10: mic. and hod. timining mostly ok., needs some tweaking of individual channels. PS timing itself looks ok however the relative timing between PS and tagger is off by 4ns(always), this inhibits to do and accidental scaling factor calibration. One block of 5 microscope columns are off regarding energy calibration, it seems the ordering is switched (this seems to be also true for the 80k run period and the 110k run period).<br />
#** ver11: looks worse regarding timing, e.g. tagger time minus RF time is off by 4ns most of the time., tagger time minus PS time is still off by 4ns<br />
#** tagger microscope walk correction does not work well for all run periods after fall 2021. Ellie Prather from UCON is working on this issue.<br />
#** Accidental Scaling Factor calibration requires Tagger and PS calibration.<br />
#** Energy calibration of tagger microscope is ok, the issue is in some "cable swap" that was not yet addressed on the translation table see: [https://logbooks.jlab.org/entry/4156839 logbook]<br />

## FCAL/ECAL: Sasha reported on the progress of the LMS five installation. At a rate of 80 fibers/day the work could be completed in 10 days.<br />
## Zisis asked about the Athens LED components. Malte answered that some [https://www.satisled.com/shop/1206-smd-led-diode-lights-chips-emitting-white-red-green-blue-yellow-purple-pink-lot-1k-1000pcs-637?category=71#attr=4074 board components] were purchased and this was useful. <br />
## BCAL<br />
# Calibration: <br />
## Igal reported that the BCAL calibration will be completed by the end of March and PrimEx by mid April. CPP cooking by April 1.<br />
## Ilya is working on fine corrections to the non-linearity. He examined the time shift vs shower energy. Sean asked about the time shift vs RF. Time-walk was discussed.<br />
# Monitoring<br />
# Reconstruction<br />
## Sean asked Zisis about Richard's proposal on neutron studies. Zisis' group is committed to other projects, but he will reply to Richard.<br />
# Simulations: Zisis will bundle the Regina standalone code and send it to Igal.<br />

#* What is the \eta polar angle resolution? -> data/simu comparison is good? Yes above 1.5 degree w/ Compton (Drew)<br />
#* How to apply the BCAL veto? -> Dedicated simulation with recoil nucleon/nucleus allows us to determine that (Drew + Ig)<br />
#* \eta mass vs \eta polar angle after 1c fit or energy constraint behavior? -> understood<br />
#* Simulation per tagger channel or flux spectra?<br />
#* Complete quasi-free PDF needed ie Coulomb (Primakoff) and Strong => 2 or 2+ PDFs for Primakoff <br />

# Previous CPP meeting: [[Π_polarizability_Meeting_Feb_28,_2024|Feb 28, 2024]]<br />
# Announcements<br />
# Action Items<br />
# Calibrations<br />
#*TOF: Full calibration complete. Tested one run, looks very good, resolution below 100ps (for mean-time). CCDB has been updated.<br />
#*FCAL: Calibration complete.<br />
#*BCAL: Finished. Running checks now.<br />
#*CDC: calibration is done. Naomi is doing some cross checks. Naomi refined the gains based on monitoring version 10, the plots are at [https://halldweb.jlab.org/wiki-private/index.php/CDC_calibration_status#CPP_monitoring_v10 calibration status based on ver10]. <br />
#*FDC: Keigo, done.<br />
#*CTOF, FMWPC:<br />
#** Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.<br>[https://userweb.jlab.org/~ilarin/cpp/3333/ plots made for the entire group], file name legend: 1st number - MWPC#, 2nd - 24 wires group #, 3rd - one for 1...2 hits in the group, five for 10 or more hits<br />
#* Tagger-Mic, PS, TPOL: ?<br />
#** ver10: mic. and hod. timining mostly ok., needs some tweaking of individual channels. PS timing itself looks ok however the relative timing between PS and tagger is off by 4ns(always), this inhibits to do and accidental scaling factor calibration. One block of 5 microscope columns are off regarding energy calibration, it seems the ordering is switched (this seems to be also true for the 80k run period and the 110k run period).<br />
#** ver11: looks worse regarding timing, e.g. tagger time minus RF time is off by 4ns most of the time., tagger time minus PS time is still off by 4ns<br />
#** tagger microscope walk correction does not work well for all run periods after fall 2021. Ellie Prather from UCON is working on this issue.<br />
#** Accidental Scaling Factor calibration requires Tagger and PS calibration.<br />
#** Energy calibration of tagger microscope is ok, the issue is in some "cable swap" that was not yet addressed on the translation table see: [https://logbooks.jlab.org/entry/4156839 logbook]<br />

# Previous CPP meeting: [[Π_polarizability_Meeting_Feb_14,_2024|Feb 14, 2024]]<br />
# Announcements<br />
# Action Items<br />
# Calibrations<br />
#*TOF: Full calibration complete. Tested one run, looks very good, resolution below 100ps (for mean-time). CCDB has been updated.<br />
#*FCAL: Calibration complete.<br />
#*BCAL: Finished. Running checks now.<br />
#*CDC: calibration is done. Naomi is doing some cross checks. Naomi refined the gains based on monitoring version 10, the plots are at [https://halldweb.jlab.org/wiki-private/index.php/CDC_calibration_status#CPP_monitoring_v10 calibration status based on ver10]. <br />
#*FDC: Keigo, done.<br />
#*CTOF, FMWPC:<br />
#** Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.<br>[https://userweb.jlab.org/~ilarin/cpp/3333/ plots made for the entire group], file name legend: 1st number - MWPC#, 2nd - 24 wires group #, 3rd - one for 1...2 hits in the group, five for 10 or more hits<br />
#* Tagger-Mic, PS, TPOL: ?<br />
#** ver10: mic. and hod. timining mostly ok., needs some tweaking of individual channels. PS timing itself looks ok however the relative timing between PS and tagger is off by 4ns(always), this inhibits to do and accidental scaling factor calibration. One block of 5 microscope columns are off regarding energy calibration, it seems the ordering is switched (this seems to be also true for the 80k run period and the 110k run period).<br />
#** ver11: looks worse regarding timing, e.g. tagger time minus RF time is off by 4ns most of the time., tagger time minus PS time is still off by 4ns<br />
#** tagger microscope walk correction does not work well for all run periods after fall 2021. Ellie Prather from UCON is working on this issue.<br />
#** Accidental Scaling Factor calibration requires Tagger and PS calibration.<br />
#** Energy calibration of tagger microscope is ok, the issue is in some "cable swap" that was not yet addressed on the translation table see: [https://logbooks.jlab.org/entry/4156839 logbook]<br />

<br />
== Agenda ==<br />
<br />
* Review minutes from last meeting https://halldweb.jlab.org/wiki/index.php/February_12,_2024_KLONG_CPS_Design_Meeting<br />
* Review new basic 3D model and compare to Pavel's model (Pavel, Keith)<br />
** Copper Absorber updated [[media:Copper absorber.pdf]]<br />
** Tagger Hall Layout (Stephanie/Keith)<br />
** Possible cross section [[media:Baseline cross section.jpeg]]<br />
* De-gaussing of Tagger magnet (all)<br />
** Run test with an existing dipole magnet at magnet measurement (Tim, Joe Meyers)<br />
* Magnet update (Josh/Stephanie) [[media:CPS Magnet requirements.pdf]]<br />
<br />
== Minutes ==<br />
* Looked at 3D model and discussed the copper absorber geometry and hall layout<br />
* Decided it would be a good idea to 3D print the absorber to ensure we have the correct geometry and recheck thermal models<br />
* The "decommissioning" volume (<10tons) was discussed and possible plans include pre assembly outside tagger hall or assemble in place<br />
* Discussed the deGaussing of the tagger and need for reply to Patricia by March 1. The plan is to work with magnet measurement group to set up a test of a similar dipole to develop the method.<br />
* Discussed magnet design progress, Josh and Stephanie are working on details including the coil design<br />
<br />
== Action Items ==<br />
* Engineering group to meet separately to progress the detail design of the "decommissioning" section (Tim)<br />
* Josh and Stephanie to continue detail magnet design<br />
* 3D print the copper absorber to ensure we have the geometry correct (Keith/Bobby)<br />
* Run thermal models of the updated absorber geometry (Hovanes/Tim)<br />
* Develop plan for testing the deGauss procedure with Magnet measurement group and send email to Patrizia (Tim)</div>Whiteyhttps://halldweb.jlab.org/wiki/index.php/Feb_27,_2024_PrimEx-eta_(informal)_Calibration_%26_Analysis_MeetingFeb 27, 2024 PrimEx-eta (informal) Calibration & Analysis Meeting2024-02-26T14:03:37Z<p>Ijaegle: Created page with " == Time and Place == * Time: Tuesday, Feb 27, 2024 at 10:00 am EST. * Room: Online == Meeting Connections == Join ZoomGov Meeting https://jlab-org.zoomgov.com/j/1603338968..."</p>

==Problem runs==<br />
<br />
* 111137 - 111145 (target full and ready) FCAL fADC module issue<br />
** started: "10/21 Owl Sift Summary" https://logbooks.jlab.org/entry/4065653<br />
** 111137 hot channels in upper left quadrant of occupancy <br />
** 111138 - 111139 junk<br />
** 111140 - 111145 fADC module taken out of trigger, no entries in same channels of occupancy <br />
** fixed: "Day shift 10/22/2022" https://logbooks.jlab.org/entry/4066120<br />
<br />
* 111404 - 111412 (target empty and ready) FCAL fADC module issue<br />
** started: "OWL Shift Summary 11/11/22" https://logbooks.jlab.org/entry/4081215<br />
** 111404 - 111405 hot channels at top/middle of occupancy<br />
** 111406 - 111412 fADC module taken out of trigger, no entries in same channels of occupancy <br />
** 111413 junk<br />
** fixed: "Day Shift Summary" https://logbooks.jlab.org/entry/4081637<br />
<br />
* 111693 - 111694 (target empty and ready) FCAL fADC module issue, hot channels<br />
** started & fixed: "Early Riser Summary 11/30/2022" https://logbooks.jlab.org/entry/4093128<br />
<br />
== ver13 monitoring launch ==<br />
<br />
* Runs to ignore: 110469, 110485, 110486 - marked as bad<br />
* Run 111771 - looks like SC electronics weren't correctly initialized - marked as bad<br />
* This is a weird one (two) on the latest monitoring - 111404, 111405 - calibrations mostly seem okay, but the rate of good events is low. I think that the rate is thrown off by the bad FCAL fADC - could consider just tossing this run.<br />
** 111694 also seems driven by a noisy fADC<br />
** all three marked as bad <br />
* Problematic TAGM channel: 64<br />
* These runs should have been marked as solenoid off, but were not - this is fixed now - 110469-110482, 110600-110621, 111969-112001<br />
<br />
=== Notes from Beni ===<br />
<br />
* 110447-110485 - NO DATA: why are these runs in reconstruction? - check next launch<br />
* 110600-110621 - NO DATA: same? - check next launch<br />
* 110535 - LOW STATISTICS<br />
* 110987-110990 - MISSING SHORT PADDLES VERTICAL PLANE DOWN: HV trip? - bad fADC, rejecting these runs<br />
* 111206 - LOW STATISTICS<br />
* 111290 - LOW STATISTICS<br />
* 111404-111405 - NO DATA: ONLY INNERMOST FCAL RING SEEN? TRIGGER? - thrown out for trigger problems<br />
* 111430 - LOW STATISTCIS<br />
* 111694 - NO DATA: SAME AS 111404-111405<br />
* 111771 - GOOD: ALL OK - run rejected for other reasons above<br />
* 111969-112001 - NO DATA<br />

''Additional comments on low statistics runs''<br />
<br />
run 110535 according to the log book the beam was off for quite some time and they<br />
did not stop the run. So the first files contain a lot of just cosmic triggers:<br />
logbook excerpt:<br />
5:25 am End of run 110534. Start run 110535.<br />
6:10 am Beam is back!! (was down for 20 minutes)<br />
<br />
run 111206 is a 3 minute run, drop it!<br />
<br />
run111290 is 20min run mostly cosmic, forget it!<br />
logbook says<br />
09:20 No beam for last 15 minutes. Stop run 111290.<br />
<br />
run 111430: 8 minute run forget it.<br />
logbook says:<br />
11:22 Start the run 111430<br />
11:30 MCC informed that they ran with same issue again while tuning up the beam so troubleshooting the issue continuously until it is resolved<br />
11:30 Stop the run 111430, junked it,</div>Njarvishttps://halldweb.jlab.org/wiki/index.php/Run_Coordination_Meetings:Winter2024Run Coordination Meetings:Winter20242024-02-16T12:44:52Z<p>Deurpam: /* Meeting General Agenda */</p>

<!---------------------------------------------------><br />
#*Verify beam position and envelope (Hovanes).<br />
#**Ask MCC to set beam position on 5C11b to x=-0.5 mm and y=+1.0 mm.<br />
#**Ask MCC for 5C11 and 5C11B HARP. Then do our radiator HARP scan, [https://halldweb.jlab.org/hdops/wiki/index.php/Beam_Line_Detectors_Shift#Radiator_Harp_Scan see instruction]. If technical issues in doing our harp scan arise, then it may be skipped. <br />
<!----------------------------------------------------------------><br />
#**Insert profiler (no need for masking FSD when an object is inserted in the photon line), run with 1×10<sup>-4</sup> radiator and 50 nA. Beam on the profiler should be at x=0.0±0.5cm; y=0.0±0.5cm. If not, inform MCC. Keep monitoring this position; produce a strip chart and log it.<br />
#*Radiation level study (1h): if you feel up to the task, strip chart the five radiation monitors (see above) and log them. <br />
#**Run 5 min without radiator (Call MCC and ask to mask the FSD each time the radiator is moved). Beam current: 50nA. Repeat at 100 nA and 200 nA. There is no need to run the DAQ or stop the beam between each steps: the data are recorded by EPICS. However, the beam need to be off when moving to a different radiator for the next steps. <br />
#**Run 5 min with the 10<sup>-4</sup> radiator (Call MCC). Beam current: 50nA. Repeat at 100 nA and 200 nA <br />
#**Run 3 min with the 3*10<sup>-4</sup> radiator (Call MCC). Beam current: 50nA. Repeat at 100 nA and 200 nA <br />
<!----------------------------------------------------------------><br />
#* Inform Richard Jones that we are getting ready to use the Active Collimator, and ask him if he needs to check the Active Collimator with the beam. <br />
<!----------------------------------------------------------------><br />
#**keep profiler in and beam locked (MCC's duty) on the nominal 5C11b and x=0,y=0 profiler position.<br />
#* Active Collimator calibration. (<0.5h, Richard Jones).<br />
#**re-Insert the 10<sup>-4</sup> radiator (Call MCC). Use about 100 nA beam current. This will provide the Act. Col. nominal positions for its high gain values.<br />
#**Insert the 2×10<sup>-5</sup> radiator (Call MCC). Use about 50 nA beam current. This will provide the Act. Col. nominal positions for its low gain values.<br />
#**Record on the white board what is the beam position on 5C11b and Active Collimator for both for low and high Act. Col. gain.<br />
#**Once Active Collimator nominal beam position is known, retract profiler and lock the beam (MCC) on the active collimator.<br />

#GEM-TRD test (Sergey Furletov, Lubomir Penchev)<br />
#*With good transmission, we expect '''8.6kHz for PSC total rate''' for 100 nA, 2×10<sup>-5</sup> Al. radiator, 750 um converter and 5mm colimator hole. <br />
#*Standard configuration: 2×10<sup>-5</sup> Al. radiator, <font color="red"> TBD nA (50nA<I<200nA)</font><br />
#**Start with Argon/CO2 for checkout (About 2 shifts). Then switch to krypton. Gas change: 5-6h. Run with Kr until the end of the run).<br />
#**Switch to krypton: Gas change: 5-6h. Remote procedure, no need for access<br />
#**Run with Kr until the end of the run. There will be 8 Rapid Access of about 1h each (15min actual work, 45min access procedure/overhead) to switch to various TRD radiators.<br />

Attendees: Sasha, Bill, Igal, Liping, Vlad, Laveen, Zisis, Stjepan, Olga, Susan, Jane, Jon, S.T.<br />
* Chris S. fabricating dividers, George J. from detector support group testing them (134 last week)<br />
** ~100 to be tested<br />
** Fabrication quality improved (only one "bad", already fixed)<br />
* Expect to use 3x amplier ~10x10 array around beam pipe due to high rate<br />
** Also plan to run at lower HV than others<br />
* Cables/dividers installed up to third row from bottom of insert<br />
** Desigining tool for replacing dividers: laparoscopy grasping forceps<br />
** Testing dividers in place with HV (make light tight first)<br />
* LMS installation continues<br />
** Needed to order face shield due to UV light backsplash<br />
** Fibers ordered into bundles, clamped and clamps attached to plexiglas<br />
** Position of integrating sphere to be fixed<br />
** Some bad fibers identified, moved to side<br />
* S.T. showed look at simulation of a small inner TOF counter covering the hole not covered by the regular TOF<br />
** Rates in 1 mm wide strips look manageable<br />
** Need to check impact of new veto on golden channel<br />
* Beam test in March: only GEMTRD studies, nothing else turned on<br />
** Hopefully no significant activation in inner region of insert<br />
* Igal studying golden channel using low level objects (not DReactionFilter)<br />
** Chi^2 test to select best candidate per event <br />
** BCAL veto needed to get rid of &omega; background<br />
** TOF veto not as effective as originally thought after TOF bug in simulation found and fixed<br />
** Working with Daniel L. on machine learning algorithm</div>Staylorhttps://halldweb.jlab.org/wiki/index.php/%CE%A0_polarizability_Meeting_Feb_14,_2024Π polarizability Meeting Feb 14, 20242024-02-13T18:14:09Z<p>Davidh: </p>

# Previous CPP meeting: [[Π_polarizability_Meeting_Feb_7,_2024|Feb 7, 2024]]<br />
# Announcements<br />
# Action Items<br />
# Calibrations<br />
#*TOF: Full calibration complete. Tested one run, looks very good, resolution below 100ps (for mean-time). CCDB has been updated.<br />
#*FCAL: Calibration complete.<br />
#*BCAL: Finished. Running checks now.<br />
#*CDC: calibration is done. Naomi is doing some cross checks. Naomi refined the gains based on monitoring version 10, the plots are at [https://halldweb.jlab.org/wiki-private/index.php/CDC_calibration_status#CPP_monitoring_v10 calibration status based on ver10]. <br />
#*FDC: Keigo, done.<br />
#*CTOF, FMWPC:<br />
#** Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.<br>[https://userweb.jlab.org/~ilarin/cpp/3333/ plots made for the entire group], file name legend: 1st number - MWPC#, 2nd - 24 wires group #, 3rd - one for 1...2 hits in the group, five for 10 or more hits<br />
#* Tagger-Mic, PS, TPOL: ?<br />
#** ver10: mic. and hod. timining mostly ok., needs some tweaking of individual channels. PS timing itself looks ok however the relative timing between PS and tagger is off by 4ns(always), this inhibits to do and accidental scaling factor calibration. One block of 5 microscope columns are off regarding energy calibration, it seems the ordering is switched (this seems to be also true for the 80k run period and the 110k run period).<br />
#** ver11: looks worse regarding timing, e.g. tagger time minus RF time is off by 4ns most of the time., tagger time minus PS time is still off by 4ns<br />
#** tagger microscope walk correction does not work well for all run periods after fall 2021. Ellie Prather from UCON is working on this issue.<br />
#** Accidental Scaling Factor calibration requires Tagger and PS calibration.<br />
#** Energy calibration of tagger microscope is ok, the issue is in some "cable swap" that was not yet addressed on the translation table see: [https://logbooks.jlab.org/entry/4156839 logbook]<br />

*Tim mentioned that Igal started to produce some sample of bggen on nuclear targets. Some example should be available in a week.<br />
*An inaccurate material map for carbon is suspected to be the reason to cause the mass shift in the j/psi analysis. Jackson suggested a new skim is needed once the new material map is updated.<br />
*Bhesha showed some plots of the effect of the cut on proton theta angle. He also showed results on checking the consistency of the rho 0 mass on different targets and run periods.</div>Boyuhttps://halldweb.jlab.org/wiki/index.php/JEF_meeting,_February_9,_2024JEF meeting, February 9, 20242024-02-08T14:48:01Z<p>Staylor: /* Minutes */</p>
