Cf252 2017
runs
05/16/17
Two 4 in. by 4 in. scintillators, both placed 5 in from the Cf252 source, with one directly above and the other directly below the source. An OR between these two scinilators serves as the TDC start. The two TDC start scintilators are connected to the CFD with a HV of -1700 V and a threshold of 172 mV.
The neutron detector array has the exact samne configuration used during the two runs occurring on 05-2-2017 and 05-3-2017.
TDC mapping is the same as usual for neutron detector array. For the timing scintilators:
PMT above src: TDC1190[1][26]
PMT below src: TDC1190[1][25]
OR of both: TDC1190[1][27]
