Abstract

A brief description is presented for a new digital-analog unit designed for recording and processing of signals from photodetectors of an X-ray luminescent separating machine, with a software-supported choice of the diamond detection methods taking into account kinetics of luminescence. Variants of processing the luminescence signals from minerals are considered for a wide range of the luminescence intensity values. The practical results of selecting the optimal diamond detection method are analyzed.
