Operation of the National Superconducting Cyclotron Laboratory Research Facility and the Michigan State University Nuclear Science Program

美国密歇根州立大学国家超导回旋加速器实验室（NSCL）是一个用于核科学基础研究的国家用户设施。该合作协议为国家科学实验室的运作提供资金，支持其用户计划，并支持密歇根州立大学工作人员在核科学、加速器和仪器物理方面的研究。实验室的设备包括两个由国家科学实验室设计和建造的紧凑型超导回旋加速器。世界上第一台超导回旋加速器K500于1982年开始运行，世界上最大的超导回旋加速器K1200于1988年6月投入使用。一个灵活的探测设备阵列将在提议期间完成使用。届时，NSCL将成为研究核-核碰撞的一个异常强大的国际设施。高质量的光束将覆盖从氢到铀的整个弹丸质量范围，用于研究弹丸速度超过核声速和核激波压缩核材料的过渡区域的核现象。这些光束也将使对原子核结构的独特研究成为可能。回旋加速器提供了美国独一无二的重离子阵列，并与相关仪器一起，支持重离子物理领域广泛的国家用户计划。根据这项合作协议，密歇根州立大学的研究活动包括一个活跃的加速器物理研究项目。仪器开发，特别是涉及超导技术，是另一项主要活动。研究生培养是国家外语学院活动的一个突出方面。该合作协议支持大约30名研究生的住宿。

The National Superconducting Cyclotron Laboratory (NSCL) of Michigan State University is a national users facility for fundamental research in nuclear science. This cooperative agreement provides funds for operation of the NSCL, for support of its users program and for support of the research of the MSU staff in nuclear science and in accelerator and instrumentation physics. Facilities at the Laboratory include two compact superconducting cyclotrons of NSCL design and construction. The K500 cyclotron, the world's first superconducting cyclotron, began operation in 1982, and the K1200 cyclotron, the world's largest superconducting cyclotron, was commissioned in June 1988. A flexible array of detection equipment will be complete for use during the proposal period. The NSCL will then be an exceptionally powerful international facility for research on nucleus-nucleus collisions. High quality beams will be available over the whole range of projectile mass, from hydrogen to uranium, for studies of nuclear phenomena in the transition region where the projectile velocity crosses the velocity of nuclear sound, and nuclear shock waves compress the nuclear material. These beams will also make possible unique studies of the structure of nuclei. The cyclotrons provide an array of heavy ions unique in the U.S. and, together with the associated instrumentation, support an extensive national users program in heavy ion physics. The MSU research activity supported under this cooperative agreement includes an active accelerator physics research program. Instrumentation development, particularly involving superconducting technology, is another major activity. Graduate student training is a prominent aspect of the NSCL activity. Approximately 30 graduate students in residence are supported by this cooperative agreement.
