Run Planning Meeting Notes, Dec 5-Dec 11, 2018

Wed, Dec 5 at 8:45

1. 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
2. Sasha adjusted CCAL LED trigger time delay https://logbooks.jlab.org/entry/3635382
3. Production trigger rate study was performed by Sasha during afternoon and evening
4. 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).
5. 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.
6. Tagger scaler distribution shows that we have beam leakage from Hall C. https://logbooks.jlab.org/entry/3635351
