US - China Cooperative Research (Physics): Study of Very High Energy Light Particle Production in Heavy - Ion Collisions using BGO Glass Scintillator Detectors

题目：中美合作研究（物理）：利用BGO玻璃闪烁体探测器研究重离子碰撞中高能轻粒子的产生。该方案为构建大型锗酸铋玻璃闪烁体探测器以研究高能粒子的产生提供了支持。本次合作研究由美国密歇根大学Frederick Becchetti博士和中国科学院上海硅酸盐研究所尹志万、沈定中教授共同提出。密歇根大学的研究小组已经成功地测试了使用大型锗酸铋玻璃闪烁体来检测高能（e200mev）下产生的粒子。来自上海陶瓷研究所（SCI）的合作科学家在生产大而透明的锗酸铋晶体方面拥有丰富的专业知识，这是构建这种高能闪烁体探测器的重要组成部分，但尚未商业化。他们计划共同建造一个非常高能（E200 MeV）的大型锗酸铋玻璃闪烁体探测器，用于探测粒子的产生。锗酸铋玻璃闪烁体探测器广泛应用于高能物理和核物理领域，是PET扫描仪的重要组成部分。该项目的成果是一个能够检测高能（E200 MeV）下产生的粒子的装置，目前没有设备能够测量。该探测器的应用可以为提高辐射监测设备和卫星监视的探测效率提供关键数据。该项目由美国国家科学基金会和中国科学院共同支持。

Title: US-China Cooperative Research (Physics): Study of Very High Energy Light Particle Production in Heavy-Ion Collisions Using BGO Glass Scintillator Detectors. This proposal is for support to construct a large bismuth germanate glass scintillator detector for studying high energy particle production. This cooperative study is proposed by Dr. Frederick Becchetti, University of Michigan, and Professors Yin Zhiwan and Shen Dingzhong, Shanghai Instititute of Ceramics, Chinese Academy of Science. The research team at the University of Michigan has successfully tested the use of a large bismuth germanate glass scintillator to detect particles generated under high energy (E 200 MeV). The collaborating scientists from the Shanghai Institute of Ceramics (SCI) have extensive expertise in producing large, clear bismuth germanate crystals, an essential part in constructing this high energy scintillator detector, but not commercially available. Jointly they plan to construct a very high energy (E200 MeV) large bismuth germanate glass scintillator detector for detecting particle production. Bismuth germanate glass scintillator detectors are used extensively in high-energy physics and nuclear physics, and form an essential part of the PET scanners. The result of this project is a device capable of detecting particles generated under high energy (E200 MeV), which no equipment is able to measure at present. Applications of this detector can provide critical data for improving detection efficiency for radiation monitoring devices and satellite surveillance. This project is jointly supported by the NSF and the Chinese Academy of Sciences.
