Back to DVCS
Back to Daily_Run_Plan
Last update: Sunday 09-26-2010
Absolute best-case scenario:
- Monday 09-27-2010: DAY shift
- start cooling magnets
- Monday 09-27-2010: SWING (or late-Day)
- lockup
- hot checkout (MCC)
- start threading beam to the Hall
- Tuesday 09-28-2010: OWL
- start commissioning
Beam without any cryo and no target
We will start with a 5 passes beam.
- Getting beam threaded down to the dump for the first time
- Beam quality optimization study
Goal: optimize beam quality to limit noise in calorimeter
Need: working Compton photon detector with appropriate HV and threshold settings, working Compton DAQ that can provide scaler data to the appropriate EPICS channel
Contact: Eric Fuchey for Compton, Jay, MCC support for beam manipulation)
- BCM calibration
Goal: calibrate BCM readings between 0 and 20 uA, with special care to readings between 2 and 7 uA
Need: BCMs reading at least through EPICS
Method: MCC procedure (MCC-PR-04-008)
Contact: J. Roche
- BPM calibration
Goal: check response of the BPMs to know motion of the beam
Need: Harps working, BPMs reading at least through EPICS, 5uA beam
Method: For each of the following approximative beam position, record beam position with the BPMS and with the harps. Beam position : (0,0), (0,2), (0,-2), (2,0), (-2,0)
Contact: J. Roche.
- Raster size calibration
Goal: to check the raster size against effective readout.
Need: BPM calibration, 5uA, BPM readings in a coda file to be able to run spot++ (Need to define DAQ setting, from He3 wiki page : TS3??)
Method: vary the size of the raster, take one run for each of the following MCC unit raster size (3*2), (7*5), (10*8), produce spot++ image at each setting. Those settings are taken off that page [[1]]
