论文摘要
Super Tau-Charm设施（STCF）是下一代高光度电子 - 峰值对撞机设施，目前是中国基于加速器的粒子物理实验的主要选择之一。基于晶体的电磁热量表（EMC）具有未掺杂的CSI是STCF光谱仪的主要子系统。为了满足对测量精度和辐射的苦难的不断增长的物理要求，提高检测到的光产量是STCF EMC R＆D的重要任务。本文使用纳米结构的有机硅发光体（NOL）研究了STCF EMC的“传播中波长转移”方案。研究是通过蒙特卡洛模拟和实验测试进行的。事实证明，在实验中，光产率提高了1.59倍。同时，对NOL的辐射硬度进行了研究，以验证NOL的可靠性。在总电离的情况下，没有观察到性能的明显降解能力高达100 krad，远远超出了STCF的总辐射剂量，运行十年。
Super Tau-Charm Facility (STCF) is a next-generation high luminosity electron-positron collider facility and is currently one of the major options for accelerator-based particle physics experiment in China. The crystal-based electromagnetic calorimeter (EMC) with undoped CsI is a major sub-system of the STCF spectrometer. To fulfill the increasing physics requirements on measurement precision and the suffering of radiation, improving the detected light yield is an important task of STCF EMC R&D. This paper studies a "wavelength shifting in propagation" scheme for STCF EMC using the nanostructured organosilicon luminophore (NOL). The studies are performed by both Monte Carlo simulation and experimental tests. The light yield is proved to be improved by a factor of 1.59 in the experiment. Meanwhile, a study of the NOL's radiation hardness is carried out to verify the reliability of the NOL. No obvious degradation in the performance is observed with the total ionization does up to 100 krad, far beyond the total radiation dose of STCF with ten years of operation.
