Accelerator: 100 ns, 60 Hz, 15 MeV
Configuration: Collimated rear scint + 2" Aluminum brick
Rates:
- Coinc both PMTs =484/4min = 121/min
- PMT Coinc Both PMTs & DC =25/4min = 6/min
Configuration: Collimated rear scint
Rates:
- PMT Coinc both PMTs = 308/2min = 154/min
- PMT Coinc Both PMTs & DC =17/2min = 8/min
The ratio of double/triple =36/1054 = 3.1%
