Process and device for real time sorting of detection events from a gamma ray detector and correction of the uniformity of detection elements from the detector

摘要

Process for real time sorting of signals from several semi-conductor detection elements in which:a) during a calibration phase:amplitude data and signal rise time data are established for each event signal,a biparametric detection spectrum with amplitude and rise time data is acquired,a biparametric acceptance window corresponding respectively to an amplitude-rise time correlation is established, andb) during an examination phase:an amplitude, rise time data pair is established in real time for each event signal detected,the events are sorted in real time, selecting the signals according to whether their amplitude and rise time data are or are not within the window.
