To-do List

Analysis List:

1. Update MottOnline
2. Add BPM Analysis
3. Replace "PEPPo" with "Mott" in scripts, decoder, ... .
4. 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 new mode: reads integral and pedestal instead of only integral
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

9- At one time, we used minicom to hard reboot the Mott DAQ VME crate. This service was discontinued. Instead, we will use the RS232
connection on the CAEN VME64X VME8200.
