Analog Timing signals
Scope picture
Raw TDC spectrum corresponding to the above scope picture:
Applying the calibration:
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 the value of peak current was changed from 30 mA to 400 mA.
TOF spectra obtained during the run with the detector BLUB:
