摘　　要：研究了由不同闪烁体瓦片／光纤材料组成，或材料相同但构造不同的量能器模型的辐照损伤．用北京正负电子对撞机（ＢＥＰＣ）的电子试验束（１．１或１．３ＧｅＶ）辐照了十个量能器模型．通过测量在不同累积剂量和在量能器内的不同位置上的光输出，对辐照损伤作出定量分析．还研究了损伤后的恢复及损伤与环境气体的关系．通过数据拟合发展了辐照损伤对剂量及对深度断面的校正方法．Radiation hardness properties of calorimeters with different structures or different materials used for the tile/fiber were studied.Ten calorimeter modules were irradiated by the BEPC electron beam(1.1 or 1.3 Gev).Radiation damage is quantified by measurements of the light yields in various locations within the calorimeter modules at different integrated doses.We also studied the recovery process and the dependence on the ambient atmosphere.The correction techniques for dose and for depth profile were developed with data fitting.
