'''This is in progress (09-20-16 contact J. Roche)'''

Need to remove the plastic shield. <br>
Calorimeter-Target distance =6.0m<br>
LH2 target, unrastered beam (which means beam current at less than 5 uA). <br>
LHRS in positive polarity.<br>
Open LHRS collimator<br>
DAQ: DVCS config, trigger is S0+S2, autovalidation.<br>
angle<SUB>LHRS</SUB>= 32.50 [deg]<br>
momentum<SUB> LHRS</SUB>= 3.0 GeV<br>
beam energy= 6.4 GeV<br>

We will take about '''2 hours''' beam with each of the following three calorimeter angles: 21.4, 22.7 and 24.0 deg. 


The plot below shows calculation for the case where we would move the calorimeter and the LHRS for each kinematic point.
