DEVICE FOR THE SIMULTANEOUS MEASUREMENT IN REAL TIME OF THE ENERGY AND OF THE FLUX OF A MONO-ENERGETIC BEAM OF HADRONS OF LOW ENERGY

摘要

A system for measuring a mono-energetic hadron beam, characterized by including a first detection unit (10) comprising a planar sensor (12) having a sensing area (14) segmented into a matrix of pixels (16), each pixel being adapted to provide a transit signal indicative of transit of a particle therethrough, and a counting circuit (18) coupled to the sensor for providing an output signal indicative of number of particles Np of the beam crossing said sensing area in a time interval, based on the transit signals provided by said pixels, and a second detection unit (30) arranged downstream of the first detection unit (10) and comprising at least one ionization detector (31) for providing an output signal proportional to the total charge Q_ion released by the beam (B) in the ionization detector in said time interval.
