Meeting are via ZoomGov: connect (Meeting ID: 160 199 0060 / Passcode 8394)
Hall D counting room white board
Friday June 24
- Last 24h:
- Accelerator went down at 6:20 as planned.
- RF recovery coupled with trying to get more beam to Hall C did not go well. We were promised beam after 5pm, then 7, then 1030.
- Shift Summaries
- Reports
- Issues
- Plans
- Sasha - check straight target configuration
- Sasha - make new CPP configuration as requested by email
- Richard (if not done during owl) - repeat 2 rows in microscope scan
- Return to production. Cycle through 240M events for each of 45perp, 45perp, 135para, 135para, then 60M events on the AMO on the goniometer.
- Production as above should be our default for 6d, with 1d on empty target.
- Try again for the TAC run on Friday
- Commissioning steps temporarily postponed:
- Flux optimization/Act .Col. calibration
- 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 23
- Last 24h:
- Inadvertent change to tagger magnet settings backed out
- Target moved out
- Richard took the microscope scan data needs another 20 mins
- Bleedthrough beam current was very low
- Thunderstorms made TAC run impossible.
- Sasha configured the trigger for straight track running
- Beam back near midnight but ran into DAQ problems.
- Overnight empty target production
- Shift Summaries
- Reports
- From MCC: Reminder that 911 from lab phone is forwarded to normal 911 and also automatically informs the crew chief, guard shack, etc that there's an emergency, crew are CPR qualified & have AED. This doesn't happen from RC phones (or cellphones). No problem w 911 from other phone; if there's a lab phone handy it saves some time.
- Power shed 3-4pm today, beam restoration likely 5pm+.
- MCC planning to raise the current to Hall C.
- Issues
- DAQ crash ROCTRIG2 - called Sergey
- DAQ lost comms with ROCBCAL11 - stop & restart DAQ fixed this
- AD00C x position moving probably due to beam energy changing
- (Tagger NMR)
- (DIRC sensor)
- (DAQ livetime)
- (Beam position stability)
- (U1-10-TOP MPOD crate)
- Plans
- No beam until swing.
- Walk-through at 11am
- Site exit opposite Tech Center closed most of the day - need to exit by resfac or Lidl.
- Put the target back (done).
- Sasha - check straight target configuration.
- Sasha - make new CPP configuration as requested by email
- Richard - repeat 2 rows in microscope scan
- Return to production. Cycle through 240M events for each of 45perp, 45perp, 135para, 135para, then 60M events on the AMO on the goniometer.
- Production as above should be our default for 6d, with 1d on empty target.
- Try again for the TAC run on Friday evening
- Commissioning steps temporarily postponed:
- Flux optimization/Act .Col. calibration
- Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.
