Summary
- finished closing the hall about 4 pm
- set spectrometers to CAFE kinematics
- checked beam with harp scans and hole target
- checked and adjusted coincidence trigger with LH2 target
- took carbon "mean field" data
- ~10: 30 am moved to gold target
Current Status
- taking data on Au target in MF kinematic
Current Run Plan
- continue taking data on Au for MF and SRC kinematic until Friday morning or statistics achieved.
Issues/updates
- LH2 loop has a problematic fan motor controller; dumps too much power into target; current limited to ~ 20 uA; probably need to warm up LH2 before accepting 40 uA on LD2
Current Issues
Planned Accesses to the Hall
- none planned; will the LH2 warmup require an access?
