Meetings are via ZoomGov: connect (Meeting ID: 160 199 0060 / Passcode 8394)

Wednesday, August 31

Past 24 hours

TAGM HV scan (Richard)
- Beam profiler used instead of AC
AC (Nick & Richard)
Solenoid B-field ramp down at 10 am and [1]
Rate stability during empty target production run (Sasha)
CCAL behavior: scalers & temperature (Sasha)
Production runs stop at 9 am (Sasha)
More details can be found here

Issues

AC (Richard)
Beam Profiler, y-position is noisy & drifting -> switch off HV wait for a couple minutes, turn HV on (Hovanes)
SC and 3 missing channels (Beni)

Plan

Insert Be target
Replace 5 FCAL bases (Mark & Malte)
Electric work
- AC (Nick)
- SC (Nick)
Take data with B-field
- Trigger study (Sasha)
- Detector checkout (raw mode for ADCs & pi0 for FCAL)
- Physics production

Tuesday, August 30

Past 24 hours

Finish CCAL HV calibration (snake scan)
Data production: empty Be target ~0.4B evts [2] (Sasha)
More details can be found here:

Issues

Hydra
FCAL bases, 3 FCAL bases need to be replaced
CDC HV, problem HVBs I-1 and 26 (Naomi & Nick)
Y position beam instability (Churamani)
- Ext6Orb Lock turned OFF(Kiarra)
- Lock Config vs. Hall D Vertical Orbit Drift (Eric)
AC (Nick)

Plan

TAGM calibration after this meeting (Richard)
Access around 10:30 am in the calorimeter cave to repair AC (Nick)
Take data until 6 pm
At 6 pm turn off Bfield and take empty Be target data for one shift w/o Bfield

Monday, August 29

Past 72 hours

Halls in beam permit since Friday 1 pm
Beam restoration took 2 hours
No radiation study was done as advised by A. Deur
CCAL snake scan with HallC bleedthrough beam [3][4] (Drew/Sasha)
Bleedthrough was stable, no beam only for 6 hours on Sunday
TAC run with cell (-4,4) and HallC bleedthrough beam (Sasha)
Data production, Be empty target
More details can be found here:

Issues

RootSpy not working
AC not working at high gain (Nick) [5]
CDC, problem HVBs I-1 and 26 (Naomi & Nick)
3 FCAL bases need to be replaced on Wednesday or sooner if opportunistic access is possible (Mark)
Target OVC Pressure (Chris) [6][7][8][9]
Lost solenoid B-field on Sunday (Tim) [10] (it took most of the day to ramp up) [11]
Tagger dump water flow, settings needed to be adjusted to new conditions?

Plan

TAGM calibration (Richard)
Debug AC (Nick)
PS harp scan (Hovanes or shift crew)
Empty target run (shift crew)
Wednesday might be devoted to RF recovery/beam study, so halls access might be possible this day

Friday, August 26

Past 24 hours

Issues

Beam dump update. The current estimated date to fix the issue from ACC is by Aug 26 at noon
CDC, problem HVBs I-1 and 26 (Naomi & Nick)
Several HV power supply channels for CCAL were identified as not working properly. There is one broken CCAL signal cable to flash ADC (Sasha/Arshak)
Some suspicious FCAL channels (Igal)
hd_ops account does not allow login - emailed Sergey last night (Naomi)

Plan

Finish hot checkout before noon
Get beam in the hall and follows [12]
- Beam recovery may last a couple of hours
- Establish photon beam may start during SWING shift

Thursday, August 25

Past 24 hours

Issues

Beam dump update. The current estimated date to fix the issue from ACC is by Aug 26 at noon
No beam between 12 am and 8 am, Saturday & Sunday and possibly also Friday & Monday
CDC, problem HVBs I-1 and 26 (Naomi & Nick)
Several HV power supply channels for CCAL were identified as not working properly. There is one broken CCAL signal cable to flash ADC (Sasha/Arshak)
FDC chiller interlock issue (Lubomir)
Some suspicious FCAL channels (Igal)

Plan

Be ready for beam tomorrow at noon
