Upgrade of the University of Missouri Small-angle Neutron Scattering Instrument

密苏里大学研究反应堆(MURR)在1980年配备了一台小角中子散射谱仪，资金来自美国国家科学基金会拨款7710626 dmr。这笔赠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2.5×10中子/厘米秒的中子强度足够低，需要最好的检测和分析系统来进行数据采集和还原。这笔赠款将用于购买和安装一个带有相关电子硬件的二维位置灵敏探测器、一个用于数据采集和分析的微型VAX，以及为探测器提供新的屏蔽以提高信噪比。这些新增功能将为用户提供更好的服务。

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.
