Accelerator parameters:

Pulse width 2 ns

Ee = 10.5 MeV

Peak current 30 mA

QDC channel # 25 corresponds to BLUT (channel # 10 on the splitter).

QDC channels [22,26] have cross talk issues.

QDC channel # 17 corresponds to Faraday Cup (channel #2 on the splitter).

run# 8753: Production run with D2O target in:

Puls width 2 ns

Ee = 10.5 MeV

Current: during the run pek current was changed from 30 mA to 400 mA.
