keyword=Compton FADC - FastDAQ Comparison
Fig. 1 shows accdiff (the difference between two consecutive samples in
accumulator 1) for run 60264, a CODA integration run taken with the PMT high
voltage off (identical conditions to the FastDAQ run) with a 32 ms integration
time. The RMS is 3.45x10^6 (x-axis is scaled by one million before being
plotted) raw adc units. With the FastDAQ data, Gregg obtained a width of 1.7E6
raw adc units, a factor of two smaller.
