Thursday, Dec 13 at 8:45
- Wednesday - Thursday morning
- 15:40 MCC starts calibrating our ion chambers
- ion chambers were calibrated for all for radiator positions, followed by harp scans
- 18:14 requesting beam for physics
- 19:17 developing TOF HV trouble; eventually Nick had to be called; he came in and replaced a card
- there seems to have been a new CODA update been committed to the DAQ; DAQ started out not working; Sashsa fixed it.
- ...
- Issues:
- some rcdb error during run starts
- comments typed during run start don't make it into the record
- 6:30 am text message to RSC phone; can we stop that

- With a 8.9 GeV beam, the field in the tagger quad should be reduced from -4.2A to -3.1A. (R.Jones)
- run plan calls for LH2 at 5% higher temp. C. Keith says the temperature can be raised without too much difficulty. He'll leave instructions with os on Friday.
- Weekend plan (current):
- finish empty target at 100 nA on 1e-4 radiator
- ~ 9:am set up for TAC run: empty target, 2e-5 radiator, 2 nA beam; take ~ 8h ABU
- Compton: LH2 target, 30 nA, 1e-4 radiator; take ~ 8h ABU
- Target density monitoring: raise LH2 target T by 5%, 100 nA, 1e-4 radiator; take ~ 8h ABU
- another TAC run: 2 nA, 2e-5 radiator, target still at +5%????
- CompCal as TAC 2 nA, 2e-5 radiator, empty target
