Abrégé

A method for determining parameters governing the transport properties of charge carriers in an ionising radiation detector. The method involves irradiating the detector and simulating a propagation of charge carrier clouds towards electrodes of the detector, so as to compare the signal resulting from the simulation and the measured signal. This allows an error to be defined, which error is backpropagated to the site of the interaction in the detector. During the backpropagation, the transport parameters of the charge carriers are updated, so as to minimise the error. The propagation/backpropagation operation is iterative and continues until a stop criterion for stopping the iterations is met.
