An LED, fiber optic, gain monitoring system for a segmented scintillator array

A gain monitoring system, which uses light emitting diode flashers and a fiber optic light distribution system, has been developed for use with a segmented, liquid scintillator neutron detector array. The system is designed to track neutron detector cell gains without relying on the stability of any system components. Tests show that the system is capable of tracking the gains of individual detector cells to the design accuracy of 3%.
