项目摘要

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.

标题：美国-中国合作研究(物理学)：使用BGO玻璃闪烁体探测器研究重离子碰撞中极高能轻粒子的产生。这项提议是为了支持建造一个大型铋锗酸盐玻璃闪烁体探测器，用于研究高能粒子产生。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陶瓷研究所尹志万、沈定中教授共同提出。密歇根大学的研究小组成功地测试了使用大型铋锗酸盐玻璃闪烁体来探测在高能(E 200 MeV)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，这是建造这种高能闪烁体探测器的关键部分，但还没有商业化。他们共同计划建造一种非常高能量(E200 MeV)的大容量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在高能物理和核物理中有着广泛的应用，是PET扫描仪的重要组成部分。该项目的成果是一种能够探测在高能(E200 MeV)下产生的粒子的装置，目前还没有设备能够测量到这种粒子。该探测器的应用可以为提高辐射监测设备和卫星监测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联合资助。
