    摘要: Method of determination of an irradiation dose deposited in a scintillator (5) by ionising radiation, comprising the steps of: irradiating the scintillator (5) during a predetermined time; detecting a moment of excitation of the scintillator (5) with a first photodetector (11); then detecting a moment of reception of a scintillation photon with a second photodetector (14), functioning in single photon counting mode; identifying each sequence consisting of the detection of a moment of excitation by the first photodetector (11), and the detection of a moment of reception by the second photodetector (14) with a coincidence event; counting the number of coincidence events; obtaining the irradiation dose deposited during the irradiation time as a function of the number of coincidence events counted and of a predetermined proportionality factor.

    摘要: The invention relates to a static converter connected between an electrical voltage source and an electrical load, said converter including a main static conversion arm comprising an output electronic switching cell and a backup conversion arm having identical structures. The static converter includes a pair of fuses connected on either side of the main arm, and a switching circuit comprising a connection element connecting the backup arm to the connection points between the fuses and the input terminals of the main arm, such that, when a fault occurs on one of the switching cells forming the main arm, a stable conductive link is established between the two fuses, the main arm is isolated by the two fuses, and the backup arm is spontaneously connected to the output of the main arm via the conductive line and replaces the main arm.
