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
→ PDF file
- TDC cut for scintillators
- Current condition: "TDC cut on each TDC → TOF"
→ TG suggested to apply only TOF cut.
- Current condition: "TDC cut on each TDC → TOF"
- 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%.
How much is the inefficiency if two layers are required out of three layers?
- About 90%.
- Channel was converted into NPE.
