Abstract
A simple design for a pulsed light source consisting of an LED and temperature‐compensating current pump has been built and tested. The source stability has been found to depend primarily on ambient temperature change. The temperature stability of the emitted number of photons (γ?670 nm) in a 200‐nsec‐wide pulse has been measured to be 0.05%/°C. Thus in normal laboratory environments it will provide a stable reference which can be used in monitoring and calibrating inevitable gain shifts observed in photon‐counting systems. Its application to the scintillation detection of γ radiation is discussed.Keywords
