- Continue production at 150nA on diamond
- Analysis update
Tuesday November 16
- Last 24h:
- recorded 2.4B triggers, trigger counter,
- after the RF work yesterday: energy stability improved, trip rate - not much
- HallC BCM calibration didn't affect us [2]
- FCAL timing [3], [4]
- FCAL base lock-up procedure applied [5]
- rootspy/hydra issues
- writing to gluonraid5 (while CC copying on tape from gluonraid4/3)
- goniometer in undefined position?
- Issues:
- writing on tape
- Shift crew will take over servicing FCAL base lock ups. wiki instructions
- Plan:
- Continue production at 150nA on diamond
- Analysis update
Monday November 15
- Last 72h:
- recorded 6.2B triggers on diamond and 140M on AMO (starting 17:30 on Friday)
- after the colimator scan (Fri 13:30-16:30) restored old quad settings and added 10% in transmission due to position optimization
- writing on tape stopped Saturday morning (disks can take up to 3 days running)
- higher than normal trip rate Saturday/Sunday - a cavity can't be re-tuned - access to fix it at 9:00
- the only big downtime - 3h last night
- HV trips last night
- Issues:
- writing on tape
- Shift crew will take over servicing FCAL base lock ups. wiki instructions
- Plan:
- expect no beam 9-10(:30) (RF working the cavitiy) then possibly some beam during tuning
- BCM calibration for Hall C energy measurements 14:30-15:30
- Continue production at 150nA on diamond
- plan for target changes
- Analysis update
Friday November 12
- Last 24h:
- Issues:
- bad f250 in TAGH [11] - no longer an issue (Sasha power-cycled the crate)
- transmission - Hovanes will do AC scan when the beam is back after 10am - profiler doesn't lock has to be fixed at that time, as well
- Plan:
- Down starting at 10am: for 1+ hours (Hall A changes to 4 passes) - FCAL items will be surveyed
- Continue production at 150nA on diamond
- Analysis update
