Résumé

The present invention relates to an integrated circuit (4) for detecting radiation receiving, over a plurality of input channels, signals arising from radiation detectors, characterized in that said circuit includes, for each input channel, a means (10) for detecting radiation generating a detection signal when the amplitude of the signal at the input on the channel under consideration exceeds a reference value, and a plurality of analog memory units storing, at the moment of generation of said detection signal, the amplitude of the electrical signal present on an input channel and time information representative of the time of detection of the radiation, the integrated circuit further including an output port transmitting, out of said circuit, the stored analog signals and a trigger signal indicating the generation of a detection signal by each detection means.
