Tuesday, Oct 30 at 08:45
- Last 24h
- Took data when beam was available
- Lost about ~6h beam
- Hall B Spin dance: 5pm - 10pm
- Accel. issues
- Beam has been taken away ~7am this morning
- Issues and current status
- Detector is on standby (empty target, coll. blocked,...)
- Accel. changed RF recovery to " General" recovery
- Hall D is in restricted access, Tagger hall will be soon
- Shifts between 8am and 4pm are on standby
- Reports
- Plans
- Accelerator
- Recovery
- Hope beam to be back this afternoon
- Hall D
- CompCal
- Walk through
- Any other work?
- Once beam is back
- Harp scan

- Return to production data
- Accelerator
- AoB
- Free shifts available
Monday, Oct 29 at 08:45
- Weekend: 10/26-10/28
- Stable beam and smooth data taking
- Changed beam current for AMO radiator from 180nA to 200nA
- Collected ~7.5 x 10^9 evts
- Performed harp scans every evening
- Issues and current Status
- Main reasons for no data taking
- Harp Scans ~30min
- A few DAQ crashes
- Beam down times ~30min (max. of 2h without beam)
- BTA was partly not available
- Main reasons for no data taking
- Reports
- Plans
- Accelerator
- Mean studies on Monday (does not affect beam availability)
- RF recovery on Tuesday
- Hall D
- Continue production runs until Tuesday morning
- Tuesday
