- Harp scan, initially problems with GUI settings
- DAQ/HOSS problem: [1], [2]
- Start of 350nA production cycle on Saturday day shift, but beam tuning to A ongoing [3]
- Saturday swing: AC bias testing, [4], status
- MCC confused about FSD trip and goniometer movements: [5]
- Sunday 1pm: Cryoleak in 1L20, tripped pump, beam restored at 10pm
- Completed first full cycle of 4 orientations + amorphous
- Reports/Issues
- Coherent edge for -45/45: [6]
- Monitoring: Saturday 5pm, Sunday 5am, Sunday 5pm
- Run Plan
Friday, August 7
- Last 24 hours
- Diamond alignment check (Hovanes)
- Coherent edges are reproducible to about 20 MeV, tweaking may be necessary
- Add screen shots of the coherent edges to logbook
- "force para" or "force perp", as appropriate, and "save as default" for each of the four settings
- Trigger check-out (Sasha)
- TagH and PS HV scan, interrupted by pass change
- Storm, optics tuning, several issues, transformer repair
- No beam since, expected only this afternoon
- Diamond alignment check (Hovanes)
- Reports/Issues
- Remind MCC to put in dumplet when changing radiators
- BCal Pulser?
- Monitoring:
- CPP Status
- Run Plan
- Access?
- Harp Scan
- Complete first production cycle with 350nA
Thursday, August 6
- Last 24 hours
- 5th pass separator problems after thunderstorm in the evening
- Beam recovered around midnight
- Harp scan: results
- Radiation levels checked: similar to spring
- Reports/Issues
- TagM was set to high gain mode during night, saturates, no meaningful data [7]
- Diamond alignment: coherent edge too far off (Beni)
- Bleed through from Hall B
- Run Plan
- Diamond alignment (Hovanes)
- Trigger, PS, TagH check (Sasha)
- Pass change at noon
