To-do List
Analysis List:
- Update MottOnline
- Add BPM Analysis
- Replace "PEPPo" with "Mott" in scripts, decoder, ... .
- 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:
- Change Mott_SemiInt to the FADC Mode 7. This mode provides:
- Pulse integral (sum of all 4ns samples over set threshold, up to 3 pulses per window)
- High resolution time (62.5 ps resolution)
- Pedestal average of 4 samples at beginning of window.
- Upgrade the time-of-flight readout to the FADC TDC mode
- Upgrade the scalers readout to the FADC Scaler mode
- Add Block Readout
