Comprehensive Nuclear Spectroscopy Instructional Facility

圣约翰大学将购买一个锗伽马射线探测器、相关的核仪器电子设备和多通道分析器，以及一个主动-被动屏蔽，以进行高分辨率、低本底的光谱学实验。所要求的设备，当与目前的物理和生物系仪器相结合时，将提供一个完整的核探测设施。新系统将把系的光谱设备的分辨率提高到目前带电粒子系统的水平，从而使学生能够(A)在物理学和辐射生物学入门课程中看到现代核探测技术，(B)在中级到高级水平进行有意义的实验室实验，以及(C)进行与核物理相关的更高质量的高级论文项目。新设备将使目前的伽马能谱系统在初级和中级实验室中得到更广泛的使用。它将有助于振兴和扩大一些现有设备的使用，如中子发生器和PDP11/73微型计算机。计划进行几个新的实验，让学生熟悉高灵敏度光谱学的原理。

Saint John's University will purchase a germanium gamma ray detector, associated nuclear instrumentation electronics and a multi-channel analyzer, and an active-passive shield in order to conduct high resolution, low background spectroscopy experiments. The requested equipment, when combined with current Physics and Biology Department instruments, will provide a complete nuclear detection facility. The new systems will increase the resolution of the department's spectroscopy equipment to the level of present charged particle systems, thus enabling students to (a) see modern nuclear detection techniques in introductory physics and radiation biology courses, (b) do meaningful laboratory experiments at the intermediate through advanced levels, and (c) do higher quality nuclear physics-related senior thesis projects. The new equipment will free the present gamma spectroscopy system for wider use in the introductory and intermediate labs. It will help revitalize and expand the use of some current equipment such as a neutron generator and PDP11/73 minicomputer. Several new experiments are planned to familiarize students with the principles of high sensitivity spectroscopy.
