Abstract
A method for controlling gain of a scintillation detector includes using a reference radiation source and a photomultiplier tube and controlling the gain of the scintillation detector based on the reference radiation source. The controlling includes detecting change in the gain of the scintillation detector, determining an amount of the change in the gain, outputting a control signal to compensate the amount of the change in the gain, and stabilizing the gain against the reference radiation source based on the control signal. A gain control system for controlling gain of a scintillation detector includes computer-readable instructions stored in the memory for causing the processor to detect change in the gain of the scintillation detector determine an amount of the change in the gain, output a control signal to compensate the amount of the change in the gain, and stabilize the gain against the reference radiation source based on the control signal.
