Upgrade of the Princeton University Cyclotron Laboratory (Physics)

这笔拨款支持普林斯顿大学的升级 回旋加速器实验室。 升级主要包括国家- 最先进的核物理仪器和设备 research. 该设备将包括一个稀释冰箱， 促进测辐射热计探测器的发展， 用于偏振靶系统的激光器，改进的原子束 设施、相关光束线和实验室升级 计算机系统. 还包括更换 加速器系统的陈旧部件，以减少 加速器停机时间，并允许在增加射束的情况下运行 强度、稳定性和能量分辨率。 这些设备将由教师和学生使用， 研究基础物理学中的各种问题，例如 时间反演不变性和宇称不守恒 原子核相互作用过程，原子核研究 天体物理学，以及核反应和结构的研究。

This grant supports an upgrade of the Princeton University Cyclotron Laboratory. The upgrade consists primarily of state- of-the-art instrumentation and equipment for nuclear physics research. The equipment will include a dilution refrigerator to facilitate development of bolometer detectors, an alexandrite laser for a polarized target system, an improved atomic beams facility, associated beam lines, and upgrades to the laboratory computer system. Funds also are included for the replacement of obsolete components of the accelerator systems, to reduce accelerator down time and to permit operation with increased beam intensity, stability and energy resolution. The equipment will be used by faculty and students to investigate a variety of issues in fundamental physics, such as time reversal invariance and parity non-conservation in weak interaction processes in nuclei, research in nuclear astrophysics, and studies of nuclear reactions and structure.
