To-do List

Analysis List:

1. Modify decoder for the updated Mott_SemiInt mode
2. Update MottOnline
3. Add BPM Analysis
4. Replace "PEPPo" with "Mott" in scripts, decoder, ... .
5. Add delayed helicity analysis for Mott_Sample and Mott_SemiInt Modes. Delayed analysis is already included for Scalers and PEPPo_Int Modes.

Things to do to speed up the DAQ and reduce deadtime:

1. Change Mott_SemiInt to the FADC Mode 7 -- Done on April 29, 2014. This mode provides:
   1. Pulse integral (sum of all 4ns samples over set threshold, up to 3 pulses per window)
   2. Pulse time (62.5 ps resolution)
   3. Pedestal average of 4 samples at beginning of window.
2. Upgrade the time-of-flight readout to the FADC TDC mode
3. Upgrade the scalers readout to the FADC Scaler mode
4. Add Block Readout
