Zusammenfassung:The invention concerns a system for detecting neutrons comprising a main detector, an auxiliary detector and a processing chain. The main detector and the auxiliary detector each comprise a sensitive volume. The main detector is suitable for delivering a first detection signal representative of an interaction of the sensitive volume of same with photons and/or electrons, and the auxiliary detector is suitable for delivering a second detection signal representative of an interaction of the sensitive volume of same with photons and/or electrons. The main detector comprises a main conversion screen made from a first material, and the auxiliary detector comprises an auxiliary conversion screen made from a second material. The processing chain is configured to generate an item of neutron count information depending on the result of the difference between a transform of the first detection signal and a transform of the second detection signal.
