Abstract
An apparatus includes a sensor to generate a light signal in response to receiving gamma radiation, and a photo multiplier tube (PMT) that receives the light signal and generates a corresponding PMT signal. A voltage source provides a supply voltage to the PMT. The magnitude of the PMT signal depends on a magnitude of the supply voltage. A temperature sensor generates a temperature signal with a magnitude that varies with a temperature sensed by the temperature sensor. The temperature sensed by the temperature sensor is substantially equal to a temperature of the PMT. A signal conditioner modifies the temperature signal. A control circuit coupled between the voltage source and the signal conditioner receives the modified temperature signal and generates a control signal for adjusting the magnitude of supply voltage based on the modified temperature signal.
