Cf252 2017
runs
05/16/17
The following configuration was used for runs 6302 through 63??.
4" by 4" scintillators are fixed 5" directly above and below the Cf252 source simultaneously. An OR between these two scintillators serves as the TDC start. The two scintillators are connected to the CFD and given a threshold of 172 mV, and a HV of -1700 V.
The neutron detector array has the exact same configuration used during the 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 PMT's: TDC1190[1][27]

4" by 4" scintillators are fixed 5" directly above and below the Cf252 source. There is hardware coincidence between an OR of the the two 4X4 scintillators, and any PMT in the array.
