Information
- 9:30-11:20 on Jun 02, 2022 JST (8:30-10:20 on Jun 01, 2022 EDT)
- Bishnu (Hampton Univ.), Toshi (Kyoto Univ.)
Discussion
AC test at ESB

- TDC cut for scintillators
- Current condition: "TDC cut on each TDC → TOF cut"
→ TG suggested to apply only the TOF cut.
- Current condition: "TDC cut on each TDC → 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.
- Note that the trigger condition is 2 hits out of 4 PMTs.
- Efficiency
- About 90% for one PMT.
How much is the inefficiency if two layers are required out of three layers?
- About 90% for one PMT.
- Channel was converted into NPE.
- ADC sum of two PMTs
→ NPE ~ 9 which is consistent with the results obtained a few years ago.
- ADC sum of two PMTs
