Abstract
The possibility of designing a prototype of the scintillation transition radiation detector (Sci-TRD) based on a thin (∼200 μm) inorganic scintillator has been investigated. Vacuum and silicon photomultipliers have been used in the measurements with inorganic scintillator samples based on LuBO3:Ce and wavelength shifting fibers. The light collection coefficient has been measured for scintillator prototypes under exposure to X rays, and the quantity of photoelectrons has been experimentally determined by irradiating the Sci-TRD working substance with a 241Am X ray source. The electron-hadron rejection ratio of the proposed Sci-TRD is expected to be ∼30.
