Abstract
The present invention relates to a device for dosimetry monitoring of a hadron beam, comprising successive ionization chambers obtained by a series of parallel detector plates separated from each other by a gas filled gap, each detector plate having a collecting part comprising a collecting side insulated from a bias voltage part comprising a bias voltage side and arranged in such a way that the collecting side is facing the bias voltage side of a subsequent detector plate, the resulting assembly of these detector plates forming a plurality of ionization chamber cells, the thicknesses and the choice of the materials of each layer constituting each detector plate as well as the gap of an ionization chamber cell have been selected in order to satisfy the condition that the water equivalent thickness of cell is equal to the length of said cell.
