Description
A system has been built and operated which monitors the gains of 318 lead-glass counters as a function of time with an accuracy of 1-2%. The light source is a single high-intensity yellow light-emitting diode (LED), and the light is transmitted to each of the counters by low-attenuation plastic optical fibers. The intensity of the LED light is measured by a reference scintillation counter whose gain is known from frequent 241Am-NaI light source and cosmic ray measurements. Details are presented of the system and of its performance during a nine-month experiment at SPEAR. (Auth.)
