Wed, Dec 5 at 8:45
- Several items were fixed during a controlled access in the morning
- Amorphous radiator ladder by Hovanes and Scot
- Colin replaced a few bad FCAL bases
- Sasha checked one noising CompCal channel and found out that it was caused by the FADC baseline
- Sasha adjusted CCAL LED trigger time delay https://logbooks.jlab.org/entry/3635382
- Production trigger rate and CompCal rate study was performed by Sasha during afternoon and evening, https://logbooks.jlab.org/entry/3635399, https://logbooks.jlab.org/entry/3635391
- MCC plan for the coming week
- MCC will continuously deliver beam throughout the rest of week with 1.83 GeV/pass (10.3 GeV for Hall D).
- On Dec 9 (Monday), the beam will be off at 6:00am. MCC will change energy to 1.61 GeV/pass (9 GeV for hall D). This process is planned for three days (DeC 9-12).
- Jay Benesch has initiated a discussion with a group of experts to investigate the feasibility of monitoring 1-2 nA beam current for Hall D.
- Tagger scaler distribution shows that we have beam leakage from Hall C. https://logbooks.jlab.org/entry/3635351
- We have been taking Compton production data on LH2 target since midnight.
Wed, Dec 6 at 8:45
- Several items were fixed during a controlled access in the morning
- Change electronics for DAQ by Sasha
- Calibrate He level DP for solenoid magnet by Marc and Scott
- A few hours used to test newly updated DAQ by Sasha and Ben
- ~5 hours no beam from late afternoon to evening
- Finish CompCal scan during owl shift
- Colin and Josh adjusted FCAL high voltages for the inner four layers of counters based on the gain factors provided by Ilya.
