Setup
In the setup of the scintillation detector, there are two PMT's and a trigger. The PMT's are placed on either end of the 100" detector and the trigger is placed in the center. While one PMT is being tested, the other is kept at a voltage of -1700 V. The trigger is always kept at -1300 V. There are three channels being read in from the detector: (1) left PMT x right PMT x trigger, (2) left PMT x trigger, and (3) right PMT x trigger. So, dividing channel 1 by channel 3 will yield the count efficiency of the left PMT and, likewise, dividing channel 1 by channel 2 will yield the count efficiency of the right PMT.
Left PMT
Right PMT
