Entry number 335830

Status: 
Today we have changed the experiment configuration to DVCS kinematics at
Q2=2 GeV2, W2=4.4 GeV2 (high energy setting). At 1 uA on the liquid H2
target, the electron rates are about 70 Hz. Presently, we are running
with an HRS only trigger (but reading out the calorimeter).

A new firmware has been installed on the ARS - some problems have been
improved, others not. Dead time issues also need more investigation.

Plans:
For the remainder of Wednesday Swing shift we will continue to take DVCS
data at 1 uA.

At the beginning of Thursday Owl shift, we should switch to the target
boiling study (the detailed plan will be posted on the white board). If
the boiling study is completed before the end of Owl shift, we will
revert to DVCS data.

Tasks for Thursday Day: 
1. Fill Moller (Moller crew)
2. Check scaler cabling in HRS (Charles)
3. Dead time investigation
4. Potential Compton tuning

Access for 1 and 2 will likely be in the morning to try and take
advantage of the brief beam studies period.
