Hall D counting room white board
Back to Run Coordination Meetings:Fall2022
Thursday Dec. 1st
Last 24h
- Wednesday started with production on empty target. It was an efficient day, with 17.1h of ABU (7am-7am).
- 9:10am-11:30 Rapid access to change fadc for FCal and FDC, and fill the target.
- Filled the target, from 10am-1pm. It took 3h to reach nominal density, and the first production runs are done while it was still filling. Target status indicated that it was full&ready by 11:30am.
- Hall A re-started running at 17:48. A consequence is that the Hall D beam energy was quite instable from 6pm (Wed.) to 1am (Thursd.), with total drift of about 14 MeV.
Reports
- PrimEx Analysis progress (Drew)
Issues
- The new FDC fadc is worst than the one replaced (Naomi/Lubomir). The problem is only for raw mode run.
- Many cdc p_diff alarms (e.g. 0.8 alarm/hour during swing and owl shifts) leading to runs often shorter than 2h (this has already been discussed several time. This is just a report).
Run plan
- Hall C is expected to be back to running during swing shift today.
- 20 min test at low beam current/high Active Colim. gain to see if adjustment are needed (A. Somov)?
- Last harp scan was done on Nov. 21st. Should we do a new one? (Transmission is fine.)
- Luminosity study?
