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 =5.5m
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= 38.04 [deg]
momentum LHRS= 2.127 GeV
beam energy= 6.4 GeV

We will take about 1 hour beam with three calorimeter angles: 26.5, 25 and 23.5 deg.
