Beam Tests of the Scintillation Detector Based on Strong Scattering Media

The opaque scintillator detector is a novel concept of a new generation of position-sensitive detectors. The main idea is to localize the light near the point of its scintillation using an optically scattering medium. The first published results by the LiquidO Collaboration are based on the application of an opaque liquid scintillator. Our approach suggests the usage of media based on a solid granular organic scintillator and an array of WLS fibers with SiPMs as photodetectors. The report describes new results obtained during the beam test of different configurations of scintillating and scattering media with external proportional chambers as a tracking system. The results of the media comparison and the estimation of the track reconstruction accuracy are presented.
