keyword=Compton FADC DAQ ProgressThe Compton FADC DAQ looks like it is working at high rates (90uA beam) for sampling mode. The first figue is a pulse heights spectrum. Black is laser on and red is laser off. High background is due to a bad beam tune, I believe.
The DAQ doesn't seem to be working in accumulator mode still. The second figue is a display of the problem: it is a pairwise difference between accumulator values. The large number of zeros is due to the fact that sometimes the accumulator data does not change between two MPS's.
