  • 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 ?
Note: we are actually add a ADC card into ROC4 since there is a spare one in ROC3 Slot21, which is not included in the CRL code. We can simply take it out and put it in ROC4, 
then move the Cereenkov cable to this card.
  • 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.
