Abstract
The invention concerns a device for analyzing a particle beam comprising at least one detector including a fiber-optic network, the network of parallel fibers comprising at least one first plane of parallel optical fibers oriented along a first direction X; the detector is designed to produce a light signal when the particle beam passes through the fiber-optic network, an image sensor coupled with the detector so as to output a signal representing characteristics of the light signal. The invention is characterized in that the image sensor comprises a CCD or CMOS sensor, wherein the ends of the fibers of the fiber-optic network are designed to form an image of the light signal in the plane of the CCD or CMOS sensor.
