To-do List
* Repair or replace bad connection at patch panel of detector signals coming from downstairs
* Analysis List:
- Add delayed helicity analysis for Mott_Sample and Mott_SemiInt Modes. Delayed analysis is already included for Scalers and PEPPo_Int Modes.
- Add BPM Analysis
- Modify decoder for the updated Mott_SemiInt mode. Started: /work/idaq/Mott/Analysis/1, Runs: 7642, 7672.
- Update MottOnline
- Replace "PEPPo" with "Mott" in scripts, decoder, ... .
* Things to do to speed up the DAQ and reduce deadtime:
- Use the new SemiIntFast Mode:
- Upgrade the time-of-flight readout to the FADC TDC mode
- Upgrade the scalers readout to the FADC Scaler mode
- Add Block Readout
- Reduce the Mott Trigger rate by rejecting low energy electrons or dump events:
- Increase E-detector discriminator thresholds
- Veto dump events using beam timing signal
