- Cable/HRS motion: add cable length and re-route the needed cables. Disconnect the others ?
- Left cerenkov overflow: move ADC from ROC 3 to ROC 4. Could we split the signal between the existing ADC in ROC 3 and the ADC in ROC 4 ?
- Deadtime:
- remove the sequencer reading of BB and only read the main trigger module. - or set hight threshold on unused channels.
- Right arm Shower block 76 missing signal: check that it is at the bottom of the acceptance if cannot be fixed.
- Right arm S1: one channel is noisy.
- Right arm Cerenkov:
- multi-peak in the TDCs: gate width problem ? - no obvious single photon electron peak in ADCs: increase HV.
- Right Q3: run Q3 at momentum ?% lower for each momentum setting.
