  • 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.
