摘要

这项工作的目的是研究在类似于低温闪烁测热计的条件下改善光收集的可能性。采用不同形状的CaWO4晶体(圆柱形、六角形和立方棱镜)、反射镜材料和形状、光学接触和表面条件(抛光和扩散)测量了闪烁探测器的能量分辨率和相对脉冲幅度。利用ZEMAX代码模拟光采集。

Optimization of light collection from oxide CaWO4 scintillators

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.
