Abstract
A nuclear detector and a circuit connect in a feed back loop to stabilize gain. The circuit defines two intervals about the capture reaction peak of a pulse height spectrum of neutron counts made by the detector and determines the number of counts occurring within the two intervals. The circuit connects to a high voltage source that powers the detector and adjusts the voltage to compensate for any shift of the pulse height spectrum due to electronic drift, for example. The circuit comprises discriminator circuits, a microprocessor, or a digital processor, for example.
