TDC mapping

TDC mapping is the same as usual for neutron detector array.

For the trigger scintillators:

PMT 6" above src: TDC1190[1][27]

PMT 6" below src: TDC1190[1][25]

6655

Two 4X4 inch scintillators are used as a fission trigger. One is fixed directly 6" above and the other 6" below the Cf252 source. The trigger PMTs are fed through a CFD with a threshold of 30mV. A hardware OR of the two trigger scintillators is placed in hardware AND with any PMT in the array. The HV of the trigger is set to -1650 V.

6656

Bad run

6657
