NEW METHOD OF OBTAINING ORGANIC POLYCRYSTALLINE SCINTILLATORS

Abstract

One of the disadvantages of polycrystalline scintillators is a significant degradation of their scintillation and optical characteristics with an increase in thickness of a scintillator. This work proposes a new approach to obtaining the initial material for polycrystals based on p-terphenyl, in which zone melting and an additional stage of reverse movement allows producing material for pressing in the form of an ingot. This method of producing polycrystals provides a significant improvement in their scintillation and optical haracteristics in relation to existing analogues.
