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]]
