Radiation sensor based on inorganic scintillator with fibre readout for high energy radiography

Abstract This paper discusses the development of a new detector for high energy photon radiography. It is based on an inorganic scintillator optically coupled to a ribbon of fluorescent optical fibres. The basic configuration is first briefly described. An investigation of the principal properties of the scintillators used for the detector is reported next: the emission spectra, the optical transparency, the radiation resistance tested by means of a 60 Co source and an 18 MV linear accelerator, etc. Detailed characterizations of these scintillators have been realized and complete experimental results are presented. The basic configuration of a high energy X- or γ-ray detector has been presented. Some important properties of two scintillators likely to be used for this sensor have been investigated. The major experimental results have been shown and discussed.
