The present disclosure relates to a radiation sensor. In one implementation, the sensor may include a radiation detector array having a plurality of pixels; at least two readout connectors having a plurality of contacts, each readout connector being configured for receiving a readout module; a routing circuit having conductors configured for routing electrical signals from each of the plurality of pixels to a corresponding contact of one of the readout connectors. The plurality of pixels is grouped in two or more groups of pixels, at least two pixels of a first group of pixels being separated by at least one pixel from another group of pixels. The routing circuit is configured for leading pixels of the first group of pixels to a first readout connector, and pixels from the other group of pixels to a second readout connector.

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.
