Beamline U2B at the National Synchrotron Light Source is being designed and built as an infrared beamline dedicated to the study of biological problems. During the winter shutdown of 1996, the horizontal acceptance of the U2B beamline was increased from 10 to 45 milliradians, in order to increase the overall flux of the beamline, especially in the far infrared. A wedged, CVD diamond window has been installed to separate the UHV vacuum of the VUV ring and the rough vacuum of the beamline. The rough-vacuum mirror box, which will accept the infrared light out of the VUV ring, has been installed. Design of the remainder of the beamline components has been approved and parts are on order. The infrared spectrometer has been purchased, Hinstalled, and is running with an internal infrared source until Hbeamline construction is complete. The spectrometer is a Nicolet HMagna 560, equipped with interchangeable (1) KBr and silicon beamsplitters and (2) MCT and DTGS detectors. These beamsplitter/detector combinations permit data collection in the mid-H(650-4000 cm-1) and far- (10-650 cm-1) infrared regions. Plans are Hunderway to modify this spectrometer for in-vacuum operation and step-scan capabilities. A NicPlan infrared microscope, equipped with a video imaging camera and motorized x-y sample stage, is included in the Nicolet system for infrared microspectroscopy. Finally, 300 ft2 of laboratory space has been awarded to the biological infrared program for sample preparation and characterization.

国家同步加速器光源的光束线U2 B正在被 设计和建造的红外光束线，致力于研究 生物问题。 在1996年冬季关闭期间， U2 B波束线的水平接受度从10提高到45 毫弧度，为了增加光束线的总通量， 尤其是远红外线。 楔形CVD金刚石窗口已被 安装分离的VUV环和粗糙的超高真空 光束线的真空度。 粗真空镜盒， 接受红外线照射的真空紫外环，已经安装好。 束线组件其余部分的设计已获批准 零件也在订购中 红外光谱仪已购置， Hinstalled，并使用内部红外源运行，直到 光束线建设完成。 光谱仪是尼科莱 HMagna 560，配备可互换的（1）溴化钾和硅 分束器和（2）MCT和DTGS探测器。 这些 分束器/检测器组合允许在 中-H（650-4000 cm-1）和远-（10-650 cm-1）红外区域。 计划 是汉威修改这一光谱仪在真空操作， 步进扫描功能。 NicPlan红外显微镜，配备 包括视频成像摄像机和电动x-y样品台， 用于红外显微光谱学的尼科莱系统。 最后，300平方英尺 的实验室空间已被授予生物红外 样品制备和表征程序。
