Saturday, October 22
Past 24 hours
- past 24 hours we collected ~3.43B total triggers on the He4 target with 200nA beam.
- Starting from run_num 111140 one of FCal fADC is broken
- Beam was OFF from 16:37 till 19:58 issues with RF 1L10 HV
- After Beam is back continued taking data at 200nA FULL target
- ~00:15 DAQ rate dropped to 0kHz, Contacted to Sergey, 1st power cycled rocTOF2, which brings trigger rate to 12.5kHz, but still way far from nominal 50kHz
- It turns out one of FCAL outer ring fADC is broken (trying to reach expert to replace it), will continue running with this condition until it's been replaced

Issues

- https://logbooks.jlab.org/entry/4066109 ->Gloun-03 reboot
Plan
- Continue taking production data at 200nA with FULL LHe target over the weekend.
Friday, October 21
Past 24 hours
- Continued taking data at 200nA with EMPTY Target Cell till ~15:00, collected ~0.65B events, overall collected data for past period 1.533B events
- 15:00 Beam was OFF for ~2.5 hours for Injector Restoration
- At 16:10 started filling the target with LHe
- ~17:40 Beam was back, started collecting data with 200nA and FULL target
- 17:58 FDC:hv:2:c3:3n channel HV tripped, tried to turn it ON, with different ways, but continuously it was tripping, contacted to Lubomir he changed the HV from 500V to 400V https://logbooks.jlab.org/entry/4064442
- 19:20 Target alarm comes ON, the Pulse Tube Refrigerator(PTR) was switched off resulting in increase of the target cell temperatures from 4.27 to about 4.6 K
- Same Target Issue happened at 20:50 again, switched back ON the PTR, and in both cases contacted to Chris Carlin, he will keep an eye on it
- 22:10 asked for Rapid Access to let Chris Carlin take a look on the heater/cooler control box
- The CDC Pressure Alarm is coming ON more frequently than it was
- Collected data for LHe ~1.9B events

Plan
Continue running on the FULL LHe target at 200nA
Thursday, October 20
Past 24 hours
- Beam was Off most of the day starting from ~7:30am for "ARW Tour and Associated Maintenance" and VCG1L1210(SRF Insulating Vacuum)
- During dawn time Mark and Malte replaced some Fcal bases (2?)
- Vlad and Arshak did some alignment on the prototype
- Kondo conducted some work on GEM-TRD
- Restored Beam to the Hall-D at ~22:30, after 15 hours of downtime
- After Beam restoration Harp Scan was performed and started run on the Empty LHe4 Cell target with 200nA
- Collected for about 0.3B events
- At 7:45 meeting informed MCC about beam position instability
Shift Summary
Issues
Plan
Continue running on the Empty target at 200nA
