Meeting are via ZoomGov: connect (Meeting ID: 160 199 0060 / Passcode 8394)
Hall D counting room white board
Friday June 17
- Last 24h:
- Tagger voltage alarms
- Nick changed card and slot again. Same issue. He set the max voltage to 1100 V so an overvoltage is less serious. The next step is to change the crate which would take a shift and need 2 people.
- Hovanes turned counters off
- Beam returned at 11 pm.
- Harp scans performed [1][2][3]
- Beam envelope looks good
- No CH edge observed. Hovanes helped to get diamond aligned overnight.
- Ran quasi production for NPP. Pressure change CDC alarm twice.
- Tagger voltage alarms
- Reports
- From PD-RC 7:45 meeting.
- Spreadsheet with list of runs
- From PD-RC 7:45 meeting.
- Issues
- 24 tagger channels off
- Plans
- Flux optimization/Act .Col. calibration
- Trigger development for TOF trigger
- Commissioning steps temporarily postponed:
- PS and TAGH HV scans
- Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.
Thursday June 16
- Last 24h:
- No beam since last meeting
- Still getting tagger voltage alarms (should we just turn those counters off?)
- Reports
- From PD-RC 7:45 meeting.
- Beam will be gone until Swing Shift at least
- Spreadsheet with list of runs
- From PD-RC 7:45 meeting.
- Issues
- High trigger rate in CTOF
- MWPC #6 window cover removed. If successful, great. Otherwise, attempt to move helium bag downstream.
- High trigger rate in CTOF
- Plans:
- Upcoming Items:
- PS and TAGH HV scans
- Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.
- Tagger Access:
- Change HV crate (Nick, Chris)
- Install helicity fibers and connect to DAQ
