The University of Missouri Research Reactor (MURR) was equipped with a small angle neutron scattering spectrometer in l980 with funds from an NSF grant DMR 7710626. This grant will allow an up-grade of that facility to make it more useful to the researchers. The neutron intensity of 2.5 X 10 neutrons/cm sec on the sample is sufficiently low to require the very best detection and analysis system for data acquisition and reduction. This grant will fund the purchase and installation of a two- dimensional position sensitive detector with associated electronic hardware, a microVAX for data acquisition and analysis, and new shielding for the detector to increase signal to noise. These additions will provide much better service to users.

密苏里大学研究堆 (MURR) 在 1980 年配备了一台小角中子散射光谱仪，资金来自 NSF 拨款 DMR 7710626。这笔拨款将允许对该设施进行升级，使其对研究人员更有用。 样品上的中子强度为 2.5 X 10 个中子/厘米秒，足够低，需要最好的检测和分析系统来采集和还原数据。 这笔赠款将资助购买和安装带有相关电子硬件的二维位置敏感探测器、用于数据采集和分析的 microVAX 以及用于提高信噪比的探测器新屏蔽。 这些新增内容将为用户提供更好的服务。
