Abstract: A device that processes a signal delivered by a radiation detector includes a circuit that delivers a voltage pulse whose amplitude is proportional to a charge detected by the radiation detector. The device also includes an analog to digital converter to digitize the voltage pulse at a given sampling frequency and delivers a corresponding digital signal to a processing circuit. The processing circuit reads the digital signal, computes a temporal variation rate of the digital signal and captures the digital signal when the temporal variation reaches a threshold.

Abstract: A method for exploiting a signal provided by a detector is disclosed. For one embodiment, the time spent by at least one part of the signal above a value S0 of a first threshold is determined. The charge corresponding to the part of the signal during the time spent above the value S0 of the first threshold is determined. A new value S′0 of the first threshold as a function of the charge and the time spent above the value S0 of the first threshold is determined. The steps of determining the time spent by at least one part of the signal above a value S0 of a first threshold and determining the charge corresponding to the part of the signal during the time spent above the value S0 of the first threshold are reiterated at least once using the new value of the first threshold.

Abstract: A method for characterizing nature of a material, including: providing at least one sample of the material between an X-ray source and a detector; using the X-ray source to make N X-radiation spectra transmitted through the material, each for a time; calculating transmission function of the material as a function of energy or the detection channel; and in each of at least two energy zones, calculating the integral of the transmission function, thus forming at least a first transmission coefficient and a second transmission coefficient.
