摘要
研究了反射层材料、光耦合剂以及晶体表面形态等对25.4 mm×25.4 mm圆柱形晶体样品的闪烁光收集效果的影响,研究结果表明:较有效的光耦合剂为折射率1.54的光学有机硅胶,反射层材料为聚四氟乙烯微粉,闪烁晶体表面形态为入射面粗糙,侧面和出光面抛光。
The performance of the LaBr_3:Ce crystal packaged with several different light-reflecting materials,optical couplants and surface treatments were studied experimentally.The results demonstrate that PTFE micro-powders should be used as reflector,optical organic silicone with refractive index of 1.54 as the couplant,and the flank and out-light surface of the crystal should be polished,but its incident plane be roughed.
