Agenda
- Announcements:
- Installation complete!
- North OB water leak: initial rate, after 1 week, after 2 weeks
- North OB LED test: before water fill, after water fill
- South Mirror box: assembly and installation, potential mirror issues and remedies
- South OB LED test: before water fill, after water fill
- Comparison of LED occupancy with and without water filled (Bill)
- FPGA temperatures in EPICS and now give an alarm if they exceed 60 C.
- DIRC moved to beam position
- Surveys are complete: initial values consistent with Spring 2019 surveys
- Readout/DAQ tests and issues (Justin, Bill, All)
- Missing pixel and appearance of dummy pixels
- Poor livetime when EPICs IOC is running at 100% CPU usage, crate controller CPU replaced (with 8 cores) problem resolved
- Missing module due to HV connector failure. Swapped to a spare connector and resolved
- Max LV terminal output during pedestal calibration, and further evaluation
- Spare electronics (Bill, Andrew)
- Fall 2019 Run Plan (All)
- Plan for informal DIRC meetings at 10 am on Tuesday/Thursday during the run (Dec 3-19): The goal is to update those outside JLab about progress and coordinate analysis work.
- GEM/TRD setup
- Installed GEM/TRD position and plane labeling
- Spring 2019 DIRC Commissioning Analysis (All)
- Merged ROOT TTrees: /volatile/halld/home/jrsteven/RunPeriod-2019-01/recon/analysis_REST/ver01_pass00/merged/
- Existing simulation samples (10M events of ρ and φ samples): producing ROOT TTrees now with additional information on truth-level extrapolated tracks.
- /volatile/halld/home/gxproj7/dircsim-2019_01-ver00/gen_2pi/
- /volatile/halld/home/gxproj7/dircsim-2019_01-ver00/gen_2k/
- New simulation samples (100M events each): various job failures that Justin is still tracking down:
E*** Samples for both Spring 2019 (commissioning) and Fall 2019 (borosilicate mirrors) will be produced
