Friday, Nov 30 at 8:45
- Comp Cal installation
- Completed at 6pm yesterday
- First sight of beam (by Comp Cal): https://logbooks.jlab.org/entry/3633247
- Swing and Overnight Running
- 15 nA on Al V-wire (full running condition).
- Lost beam around 2am (due to radiation damaged valve position sensor).
- FCAL is down:
- Monitoring current draw on CAN bus [Matt]
- Rapid access is arrange between 10am - noon.
- Run Plan:

- Beam requested today: 2nA on the foil.
- Cryo
- solenoid helium fill test this morning: https://logbooks.jlab.org/entry/3633314
Monday, Dec 3 at 8:45
- Comp Cal Status
- Friday: cell-by-cell calibration
- Friday overnight: successful TAC run
- Saturday: completed cell-by-cell calibration
- Saturday overnight: no beam / TAC rate issue (due to beam characteristic change).
- Sunday: completed voltage matching
- Sunday overnight: voltage crosscheck data taken
- Data ready?
- Target
- Be target installation (tentative date is Thursday)
- LH2 Cooling and when?
- Empty target data during the target colling process?
- Accelerator
- Beam study 9am-2pm
- Energy change next Monday
- Planned hall access:
- Alex: hall tour at 1:30
- Sean/Stuart: checking the cable for the tagger hodoscope (not scheduled)
- Hall tour tomorrow?
- Other idea of using the low current beam
- Ken: The coherent peak test near the tagger hodoscope low energy boundary (preferably after the energy change) with ~2nA current
