Upgrade of the Princeton University Cyclotron Laboratory (Physics)

这笔拨款支持普林斯顿大学回旋加速器实验室的升级。这次升级主要包括最先进的仪器和核物理研究设备。该设备将包括一个稀释冰箱，以促进热计探测器的发展，一个用于偏振目标系统的紫变石激光器，一个改进的原子束设施，相关的光束线，以及升级的实验室计算机系统。资金还包括更换加速器系统的过时部件，以减少加速器停机时间，并允许以更高的光束强度、稳定性和能量分辨率运行。该设备将被教师和学生用于研究基础物理中的各种问题，例如原子核弱相互作用过程中的时间反转不变性和宇称不守恒，核天体物理学的研究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.
