    Took ~1h beam time to test a new acquisition of the compton photon detector. 
    The idea is to integrate the energy deposited in the compton calorimeter over a 
    polar window of 33ms using the HAPPEx ADCs. 
    Preliminary online analysis show a signal ~3000 channels above pedestal at 
    10uA. Pedestal fluctuations at the 10 channels level and no obvious 
    Plan is to study more carefully the systematics during DVCS by running the 
    Compton and HAPPEx daq in parallel (not invasive for the experiment).
