Hall work
- Water level sensor installation
- Total: 2 days. 1 day testing + 1 day installation
- Darkening leak check
- Total: 1 day
- Modification on vent exit to reduce FPGA temperature
- Total: 3 days. 1 day diagnose, 1 day test and 1 day installation. Excluding time for designing time.
- DIRC Diffuser seal issue
- Total: 2 days. 1 day test and 1 day installation. Excluding time for water seal test
- Contaminated mirror replacement in north upper OB
- Total: 1 days. Uninstall + Disassembly: 1 day; mirror removal + setting up clean area, mirror gluing+ curing: 3 days; silicone seal + cleaning + assembly: 1 days; installation: 1 day. Excluding time for water seal test
- Inspect the south lower OB
- 1 day
- If mirror problem, adding 6 more days for mirror replacement.
- South box module c2r18 over current limit diagnosis work
Non Hall Work
- Testing spare DIRC modules
- Control and operation
- Alarm modification strategy
- Resolving (double checking) DIRC hole in occupancy before run starts
- Dis-entangle DIRC interlock and interlock reset from FCAL and CCOM
- Individual (stand alone) SiPM TDA offset
- Tile FPGA voltage regulation issue.
- Recover loan-out (Duke SOLID group) MOROC chips
Not-to-forget items
- Re-activate tile-temperature alarm for the south box c2r18
- Including south box c2r18 fiber verification back into the DAQ starting procedure
