|The DT5790 operates upon the DPP-PSD firmware, specially developed for Charge Integration and Pulse Shape Discrimination. DPP-PSD is based on an advanced on line Digital Dual Gate Charge Integration allowing an effective data analysis even at high count rate. It performs input signal baseline calculation, self-triggering and double-gate charge integration with programmable parameters, double integration of both prompt and total charge for Pulse Shape Discrimination and pedestal subtraction for energy calculation.|

|The detection of special nuclear material has been studied with a mobile inspection system used both as a high sensitivity passive neutron/gamma spectroscopic tool and as an active inspection device using tagged neutrons. The detection of plutonium samples seems to be possible with passive interrogation, even for small samples. The passive detection of uranium is much more difficult because of the low neutron yield and of the easiness of shielding the gamma ray. However, we show that active interrogation with tagged neutrons is able to provide signatures for the discrimination of uranium against other heavy metals.
