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 cryo target
We will start with a 5 passes beam. The tasks below appear roughly in order of priority, one assumes that we have solid targets in place.
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)
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.
Center beam on target
Goal: get the beam to hit the center of the holed carbon foil Need: BPMs reading at least through EPICS, Lumi scaler readings??, Calo anode current readings??
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
- 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]]
