A method has been developed and experimental investigation conducted on time dependence of intensity of the cathodoluminescence (CL) induced in technical dielectric materials by high-energy pulse electron beam. At a LU-10 accelerator, the optical path and measuring channel were designed for remote recording CL signal. As optical sensor, a SFH203P photodiode was used with an amplifier on the basis of a HS special-purpose op amps. Preliminary study of conditions of CL registration was performed at a bench. For a number of materials, coincidence of signals of the beam current and CL, as well as dependence of CL amplitude from thickness of the CL radiator have been established. Possibility is shown to use CL signal induced by scanned electron beam for on-line monitoring the beam current density and absorbed dose distributions on the surface of a processed object.
