Abstract
A gain regulator is disclosed for use in a radiation analyzer system. The analyzer responds to a source of radiation having a known peak in its energy spectrum. Gain errors are detected by accumulating a count corresponding to the difference between the number of radiation particles occurring in windows in the energy spectrum which are above and below the desired centerline of this known peak. These two windows overlap in the area of the centerline. Gain is either incremented or decremented whenever the difference count exceeds preselected limits. The difference count is reset whenever a predetermined number of particles have been detected in either of the windows.
