Back to [Winter2016 DVCS run plan]

θ_calo [deg]= 25., θ_STAND [deg]= ??.
Need to remove the plastic shield.
Calorimeter-Target distance =6.2m
Unrastered beam (which means beam current at less than 5 uA).
LHRS in positive polarity.
DAQ: DVCS config, trigger is S0+S2, autovalidation.
angle_LHRS= 38.04 [deg] momentum _LHRS= 2.
