Previously...
- restore beam (NL vacuum/cooling issue)
- ARC energy measurement
Specific mission
- Note:
1/ HARP scan
2/ C-hole and Spot++ with BPM
(special long (30min) run: Charles request)
3/ Production
DVCS: Kin_48_4
- 15uA
- LH2 target
- DVCS ON
- Calo_theta= 10.1(deg), Distance = 2.5m (from target) - LHRS=3.36GeV, angle=24.925(deg), Q1/Q2/Q3=1916.640(readout:1900)/1600/1600 (Q1 regul.OFF)
- RHRS=2.204GeV, angle=48.75(deg)
- PreScaleR : PS1=PS2=PS3=1, && PS8=200
- PreScaleL : PS9 =1, + DVCS config.
- Raster : 2x2mm^2
BPM/Spot++ Check
- After a period of 3 hours or more without beam (like beam study, pass change,...) ask MCC to run 5uA 2 by 2 rastered beam on the carbon hole target and make sure you can see the hole (use Spot++ to analyze the C hole run)
