Abstract: Measurements of electric charges obtained by the impact of ionizing radiation on a semiconductor detector are grouped in a histogram. Calibrations and data otherwise obtained are used to obtain acceptance probabilities of measurements, which are used to construct a histogram of events by weighting the measurements so as to exclude the influence of some factors (such as diffused radiation) or on the contrary to enhance this influence.

Abstract: A method for processing a two-parameter spectrum including selecting a profile parameter for the spectrum and an initial correction function, for any profile selected according to this parameter, carrying out at least a correction operation by multiplying this selected profile by a correction function, equal to the sum of at least a portion of the already corrected profiles.

Abstract: The invention relates to a device for detecting electromagnetic radiation, in particular ionizing radiation, consisting of an assembly of juxtaposed parallelepipedic semiconductor detection blocks (1001, . . . 100m), each detection block the assembly being provided in such a way as to reduce the detection dead zone.

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: This invention relates to the field of signal processing, in particular x-ray or gamma-ray spectrometry. It relates to a method as well as a device for improved processing making it possible to correct two-parameter spectra.

Abstract: This device for detecting ionizing radiation has a stacked structure comprising a first set of electrodes, a sensing element capable of interacting with the incident radiation to be detected by releasing mobile charges (electron-hole pairs) and a second set of electrodes, said first and second sets being intended to collect the mobile charges thus released. This stack also comprises a third set of electrodes intended to measure the charges induced by movement of the mobile charges, the electrodes in said third set being separated from those that constitute said second set by an electrically insulating layer defined so as to enable capacitive connection between the electrodes of said second set and the electrodes of said third set.

Abstract: The invention concerns a method for exploiting a signal provided by a detector, in which: a—one determines the time spent by at least one part of the signal above a value S0 of a first threshold, b—one determines the charge corresponding to the part of the signal during this time, c—one determines a new value S?0 of the first threshold as a function of the charge and the time thus determined, d—one reiterates at least once the steps a and b by means of the new value of the first threshold.
