Opis
Sažetak:The purpose of this work is to study the possibility to improve light collection in conditions similar to than in cryogenic scintillating bolometers. Energy resolution and relative pulse amplitude of scintillation detectors were measured using CaWO4 crystals with different shapes (cylindrical, hexagonal and cube prism), reflector materials and shapes, optical contact and surface conditions (polished and diffused). Light collection was simulated using ZEMAX codes.
