Research in Low Energy Nuclear Physics

这笔拨款支持普林斯顿回旋加速器实验室的研究和运作。该小组将在核物理、核天体物理、基本对称性和相互作用的前沿进行测量。这些实验将扩展对核系统中时间反转不变性的研究，对β衰变中的介子交换电流的研究，以及对电子-正电子相互作用中的轴子样粒子的研究。其他实验将使用专门开发的设备来研究远离稳定的原子核的性质。使用普林斯顿QDDD磁谱仪进行的一系列测量将提供有关宇宙早期发生的天体物理过程的新日期。加速器改进和先进仪器开发的相关计划将继续进行。加速器的改进旨在提高性能和可靠性。仪器研究和开发将包括辐射热计辐射探测器的工作。除了普林斯顿大学的用户外，回旋加速器实验室还被其他大学的大量用户组用于研究和研究生培训。

This grant supports research and operation of the Princeton Cyclotron Laboratory. The group will carry out measurements at the frontiers of nuclear physics, nuclear astrophysics, and fundamental symmetries and interactions. The experiments will extend the search for time reversal invariance in nuclear systems, for meson exchange currents in beta decay, and for axion-like particles in electron-positron interactions. Other experiments will use specially developed equipment to study the properties of nuclei far from stability. A series of measurements using the Princeton QDDD magnetic spectrometer will provide new date concerning astrophysical processes that occurred in the early moments of the universe. A related program of accelerator improvement and of advanced instrumentation development will continue. The accelerator improvements are aimed at increasing both performance and reliability. The instrumentation research and development will include work on bolometer radiation detectors. The Cyclotron Laboratory is used for research and for graduate student training by a large number of user groups from other universities, in addition to those from Princeton.
