+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.
