Summary
- Re-established beam last night late swing. Had to change the positions a small amount to center the beam spot [1]
- 15uA on H during day shift. Modified the GEM HV some to improve the front tracker [2]. Finally moved up 1% more on the gas mix [3]. Settling now with SBS GEM HV off.
- Evaluate on H target the GEM gain, then proceed to production:
- 10uA on D data-taking on swing and owl.
- GEM work yesterday [4]
- ECal work yesterday [5]
- Analyzer and hodoscope work [6]
Planned Access to the Hall
Access Tuesday:
- GEMs work:
- inspect GEM HV as able
- APVs on XW L0
- ECal:
Accelerator
Plan unchanged from yesterday:
- no Wien angle change next Tuesday for Hall A pass change;
- Accelerator beam studies currently scheduled on May 19th starting at 7am
Current Run Plan
Take data at 10 uA for production on LD2: BBCal threshold at -350 mV and HCal threshold at -14 mV for now. Once per day (preferably during day shift), take a 3 hours at 15 uA on LH2 with the production settings. See also Experiment run plans.
Current Issues
- Alignment and pedestals needed for GEMs.
- GEM DAQ issues
