Cerenkov dosimetry device for detection of high energy particles has a sensor element comprising a single layer of adjacent optical fibers forming a large cross section for detection of the whole cross section of particle beams

摘要

Device comprises optical fibers (3) forming a single film (2) of optical fibers that make up a large detection area measurement sensor (4). The sensor can thus detect the whole cross section of a particle beam. For measurement of the total intensity the optical fibers are linked to a common photo-detector (10), while for spatially resolved measurement an intensity profile is generated by linking each optical fiber to a separate photo-detector.
