Back to [Run Plan DVCS 3 ]
This is in progress (09-20-16 contact J. Roche)
Need to remove the plastic shield.
Calorimeter-Target distance =6.0m
LH2 target, unrastered beam (which means beam current at less than 5 uA).
LHRS in positive polarity.
Open LHRS collimator
DAQ: DVCS config, trigger is S0+S2, autovalidation.
angleLHRS= 32.50 [deg]
momentum LHRS= 3.0 GeV
beam energy= 6.4 GeV
We will take about 1 hour beam with three calorimeter angles: 21.4, 22.7 and 24.0 deg.
