The invention relates to a matrix device for measuring characteristics of an X-ray beam. The device includes a first set of detection cells of a size different from the cells of at least one second set of detection cells. Each cell corresponds to an ionization chamber including a detection electrode. The detection electrodes of all the cells have the same effective surface for collecting charges.
