Abstract:
1. A method for real-time measurement of a local dose received by a region of a target during the bombardment of said target by an incident beam of hadrons which leads to a nuclear fragmentation in said target and generates at least prompt gamma radiations and neutrons, comprising: measuring the particles emitted by the target by collimating the region of the target; and receiving prompt gamma ray using a detector stationed at a distance L from the region to be measured of the target, said detector being associated with particle energy and time-of-flight measurement means, and determining a number of prompt gamma rays received by said detector by: where the distance L is chosen so as to make it possible to discriminate the prompt gamma rays from the neutrons by virtue of their difference in propagation speed and where a hodoscope for detecting charged particles, stationed in the beam of incident hadrons before the target, is implemented in such a way as to obtain the transverse position of the incident hadrons.
