Minutes
Attendees: Yi, Alam, Elton, John, David (JLab); Zisis, Shawn, Andrei (UofR)
- Announcements
- Action Items
- Monitoring
- Paper has been accepted. Already online. Final proofs in review
- Discussion on raw data format for flash 250 MHz
- Level-1 Trigger#Manuals
- GlueX-doc-2274 FADC125 Data Format
- Proposal to add tag=9 to Flash 250 MHz, which combines time and summed output, as proposed for the Flash125.
- Proposal accepted by group. Elton and David to meet with group at JLab to come up with definite proposal for feedback from this group
- Check dynamic range of proposed TDC time and summed signal
- Ideas for use of quality factor/pedestal bits: 10 bits for pedestal, 3 bits overflow, 2 bits quality factor.
- FCAL (John)
- Complete dark box in about 1 week
- Upstream cover ready to hang this afternoon or tomorrow
- Downstream side:
- patch panel completed
- LED monitoring cables/system done (lacking 4 external cables)
- External cables for power and control for bases installed
- Complete enclosure by installing 3 pieces of Al, planned for the next few days
- Still need to complete some re-programming of slow controls, planned for the next week
- Fcal DAQ meetings have begun to organize the readout activities with Sasha and Marc.
- Expect to turn on in about a week
- (Elton) Need to check that fire protection for the dark room is on track to be installed and ready for turn on.
- (Zisis) How was the monitoring system checked so far? (John) Temporary pulser system was used to check that appropriate LEDs light up when pulsed.
- BCAL
- Cabling is complete (except for a small section left open for access to the interior of the solenoid)
- Cooling lines are all installed, but insulation is still needed
- Nitrogen system up to BCAL has been installed and pressure tested. Flow meters need to be added to connect BCAL to the system.
- Power is installed on the south racks, north will be added shortly.
- BCAL cosmic rays (Shawn)
- Time-walk corrections are being finalized for the cosmic ray runs. Results will be shown next time.
- (Elton) What is the distribution of minimum-ionizing in the tested modules? Normalization compared reasonably week to expectation with a variation of about 15%. Angular corrections to the peaks will be done once the time-walk corrections are complete.
- Summary of tw corrections and normalization will be shown at the next meeting.
- Single fiber single-photoelectron normalization (Andrei)
- Completed a reanalysis of the number of photoelectrons for fiber QA tests
- Latest analysis was more systematic than previous and is now completed. Need final iteration and an update to the documentation
- Reconstruction and Simulation
- Giovanni has obtained his JLab account and is now starting to use the JLab cluster
- TDR update
- Elton: Hall D needs to comply with the JLab Configuration Management program. For this we will summarize each subsystem in description tables. The collection of summaries will be controlled by Eugene and a system owner. Changes need to be documented and signed. Elton has started on a draft using the BCAL and FCAL as examples and would like feedback from others in the group. Will distribute draft to John/Matt and Zisis for comments.
- Calibration of Calorimeters
- Any other business
