Abstract
The present invention relates to a dosimetry device for an energy particle beam from a source and including at least two ionization chambers, each of which includes a collector electrode and a polarization electrode, said electrodes in each ionization chamber being separated by a gap including a fluid, an energy beam from a single source passing through said ionization chambers, the device being characterized in that said ionization chambers have different charge collection efficiency factors. Said calculation algorithm for the dose rate deposited by said beam is based on the measurement of an output signal in each ionization chamber of the device and on a □gain□ factor related to a first ionization chamber, said □gain□ factor being theoretically predetermined on the basis of said intrinsic and/or extrinsic parameters of said ionization chambers.
