Run Plan (DVCS3)

Assume: -longitudinally polarized beam -max 20 uA but for short times when it can go higher -7.7 GeV-4 pass or beam

Commissioning/ Calibration

Beam instruments

BPM/Raster checks/Beam centering

1. Check that harps are functional
2. Send unrastered beam to the four corners of a 2*2 mm square around assumed (0,0) position (as defined by RAD reading in beam dump). At each position compare harps against BPMs reading.
3. Check size raster using the spot++ tool. Pending target boiling studies result, we will use a 2*2 mm raster.
   JR: Is it a matter to ask MCC for a 2*2 mm raster or does the info needs to go to them in a more "native" unit. Do we have a choice of frequency?

BCMs

Use the procedure that is under .....
Need: To insure that minimal beam lost in the machine can be measured, beam that would go up to about 100 uA. We also need to be the only hall receiving beam.
Open question: Do we want to calibrate against the Unser monitor?

Moeller

The proposal goal calls for ΔP/P=1%.
Open questions: How often do we want to measure the polarization?
