RC Meeting Information
RC Daily Meetings are at 11:00 (am) via Zoom and in person in the counting house meeting room (2nd floor)
- Zoom remote connection information: https://logbooks.jlab.org/entry/4229331
- RC meeting today
Useful Links
Current Status
- Production on KinC_x50_2 and _2'.
- Saturday 09 Dec: 07:00-09:00 Separator repair work. Beam restored to HallC ~ 09:30
- Sunday 10 Dec: HMS Q3 & Dipole tripped at 11:19 (run 3510) Restored directed to set points (Run 3511, 3512) Ramped to MOL and back to set point at 14:00
Current Run Plan
- Continue run plan: https://hallcweb.jlab.org/wiki/index.php/Short_Term_Run-Plan
- cycle KinC_x50_2 then KinC_x50_2'
- Only need four 1-hour production runs on LD2 for each cycle of each setting.
Notices in Effect for Shift Crew
- All shifts should come in as planned.
- Heidi on vacation 7-13 Dec. Contact Steve L for cryo during that time.
- cc Heidi & Steve Lassiter on any cryo logbook entry (fansler@jlab.org, lassiter@jlab.org)
- Physically verify green led of gas flow and BCM temps in electronics room
- Record HMS (electron) tracking efficiency from each 50K replay report
Current Issues
- On call list seems incomplete and should be addressed by the Hall: https://logbooks.jlab.org/entry/4230495
- We need other indications of this interlock. In Hall A, we have it shut off detector HV via the alarm handler, and we have a flow rate alarm. Seems the useful PV values have not been working since 1-Sept.
- NPS PMT/Base failures are propagating into columns 9, 10, 11, 12
- Calo Temp sensor interface failed yesterday around 16:30.
- Remote restart by Aaron Brown not successful
- Access to Hall, Unplugged and replugged AC power https://logbooks.jlab.org/entry/4232489
- Beam recovery took another ~2 hours
Planned Access to the Hall
- perhaps opportunistic access Monday to disconnect some noisy signal cables to FADC from empty channels.
Planned Accelerator Configuration Changes
- We will run until 07:00 Dec 15.
- Target will be warmed up and parked.
- Hall will remain in Controlled Access until 07:00 Dec 19
- Beam studies (Day Shift) Dec 19 will send beam into hall
- Hall will return to Controlled Access at 16:00 on Dec 19
Special Requests
- Plan for Moller Dec 13 or 14 (single HWP setting)
- Calorimeter energy resolution studies
- Analyze pi0 mass resolution as a function of pi0 energy
- Analyze pi0 mass resolution separately for high current and low current runs
