Discussion

AC test at ESB

　→ PDF file

• TDC cut for scintillators
  • Current condition: "TDC cut on each TDC → TOF cut"
    → TG suggested to apply only the TOF cut.

• We found that an ADC of PMTs of scintillators has only pedestal
  → will be checked.
  • Note that the trigger condition is 2 hits out of 4 PMTs.
    → That's why there are pedestals in all ADCs of scintillators.

• Efficiency
  • About 90% for one PMT.
    How much is the inefficiency if two layers are required out of three layers?

• Channel was converted into NPE.
  • ADC sum of two PMTs
    → NPE ~ 9 which is consistent with the results obtained a few years ago.
