Light-Stabilized Photomultiplier Detector Assembly with Pulse- and Current-Mode Operation

摘要

This unit was developed to provide an economical scintillator detector assembly for microprocessor-controlled effluent-monitoring systems. The integral high voltage supply is controlled to maintain constant photomultipiler gain fom a pulsed light-emitting diode reference source. This control method also provides current-mode operation if high radiation levels are present. In addition, a simple comparison of the light-output pulse gives an assurance of detector operation.
