Latest revision as of 06:19, 21 March 2019

Past 24 hours:
- Acceptable quality beam established early morning around 11:00 am.
  - Beam profile and convergence by Jay:https://logbooks.jlab.org/entry/3652506
- DIRC data taking.
  1. DIRC analysis is on-going.
Issues
- Cryo Water Temperature jump to 72F (limit 70F).
  - Due to pump switch: https://logbooks.jlab.org/entry/3652512
- IOC lost communication
  - IOCHDCOL failed at 21:30. Reported to us by MCC at 0:00. Reset at 1:50 am. Hovanes verified things are ok at 3am. https://logbooks.jlab.org/entry/3652920
- DIRC SSP problem:
  - DAQ stopped twice due to the out of sync issue.
- Tagger RF time: https://logbooks.jlab.org/entry/3652533
- hdview2 is work working
Today:
- No planned access
- Opportunistic access requested by Kenoe to work on GEM.
- DIRC nominal running (MOROC threshold scan?)

Past 24 hours:
- Nominal DIRC setting collected 1B triggers
  - Switched to the higher MOROC threshold (200)
- Smooth overnight running at 180nA, coming back to the desired 225nA this morning.
- Both opportunistic accesses happened during the accelerator down time due to the bulk power supply failure.
Issues:
- Beam steered to the wrong BCM, therefore constrained the maximum beam delivered to 180nA
  - Detailed log: https://logbooks.jlab.org/entry/3653554
- Goni camera, wrong angle, did something move? https://logbooks.jlab.org/entry/3653437
- root spy crash: https://logbooks.jlab.org/entry/3653678
- DIRC SSP
  - Runs at MOROC threshold of 50 not possible due to the out of sync issue, need to be looked into
  - Out of sync over night (after switching the MOROC threshold).
- hdview2 and monitoring email working?
Plan for today:
- keep collecting higher MOROC threshold data (up to 1B triggers).
- When beam is not available, 15 min LED runs with different pulsing and trigger conditions.
- No planned and opportunistic access

Over the weekend summary:
- Quote by Eugine: "All the problems landed on other ppl's court".
  - https://hallcweb.jlab.org/doc-public/ShowDocument?docid=1010
- DIRC SSP firmware on Friday (thanks to Ben and Sasha)
- Low intensity program completed.
- HV scan: two more settings remains
- HI test on Sunday: for most of the day, we were the only hall up.
  - ToF inner layer off, DC HV reduced, Tpol excluded from the trigger.
  - DIRC and DAQ passed the test!
- Overnight: smooth 425nA scanning operation.
Monitoring
- Only 6 out of 30 root monitoring plots are fully occupied.
Plan for today:
- Hall A, B and C are down, another HI test? @900nA?
Issues:
- hdview2: hang on the 1st event
- DAQ: Randy factor cant be set and BCALroc.
- Any update on the RF issue?
Transition to the CPP

Past 24 hours
- 500 nA threshold scan: trigger rate 75k Hz
- Overnight: smooth 350nA scanning operation.
- HV scan: almost done, only few more settings remains
Data Analysis: https://logbooks.jlab.org/entry/3655915
Monitoring and rootspy:
- log from Dave: https://logbooks.jlab.org/entry/3655600
- log from Thomas: https://logbooks.jlab.org/entry/3655931
Plan for today:
- Complete HV scan and finish 350nA threshold scan.
Issues:
- Coherent peak degeneration:
  - Feb 10: https://logbooks.jlab.org/entry/3650944
  - Feb 19: https://logbooks.jlab.org/entry/3655872
- DAQ crash: rocDIRC, rocTAGMH and rocTRIG2 lost connection. Wouldn't come back after rebooting
- DIRC scalar implementation.
- Tagger cable swap: https://logbooks.jlab.org/entry/3653736
Hall access today:
- RF recovery for 8 hours.
- Mark, Colin and Beni. Restricted or not?
- Tagger Hall: restricted by 10 am for neutron detector work
Transition to the CPP
- Hall Access starting 7am tomorrow (Feb/19).
- Any running plan? As a matter of fact, yes.
- No RC meeting tomorrow.

DIRC commissioning completed, and DIRC crews are happy.
Issues:
- CSS unresponsive (5mins to open any new window): https://logbooks.jlab.org/entry/3656340
- RF problem found (Beni)
- Goniometer controller failed (Sunday afternoon) and replaced: https://logbooks.jlab.org/entry/3656044
  - Coherent peak with 17um diamond: https://logbooks.jlab.org/entry/3656353
  - Coherent peak with 47um diamond: https://logbooks.jlab.org/entry/3656361
CPP tasks and schedule:
- Revert back from the DIRC lumi settings (FDC, ToF, TAGM, TPol).
- Currently under restricted access til 12:00 pm, hall work on-going
- Lockup at noon (11:45am, MCC announcement).
- Radcon support arranged for 3-6pm
CPP run plan: https://www.overleaf.com/read/yzzgqtddbfmy
MCC whiteboard:
- MCC white board
- We have priority today
