Previously...
- MCC restore the beam Hall-A
- Spot++ for beam centering with C-hole target
- repair 5pass separator (fixed!)
Specific mission
- Note:
5pass RF separator repair
Any chance of opportunity of good beam for physics
(beam goes straight ! not through chicane)
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
- Stay on the DVCS Kinematics (Kin_48_4)
- Raster PS replace(last bin) - Y (over heat and failed)
Tentative plan
Tomorrow after beam study
1/ Arc energy measurement : Doug (Morning)
2/ Moller measurement : Sasha (Afternoon)
Friday ?
3/ Establish the beam through Compton chicane: Dave & Yves
BPM/Spot++ Check
- After beam lost for considerable time (like beam study, pass change,...)
- Ask MCC to run 5uA wth carbon hole target and make sure you can see the hole through Spot++
