In recent years there has been a growing interest in the application of X-ray scattering techniques to biomolecules in solution. At NSLS, a new undulator-based beamline, X9, has been constructed to address the oversubscribed user demand for X-ray scattering. Beamline X9 has the capability to perform small/wide-angle X-ray scattering (SAXS/WAXS) all in one single instrument. This is accomplished by utilizing a vacuum sample/detector chamber that is an integral part of the SAXS scattering flight path. This vacuum chamber allows a WAXS detector to be positioned at a close distance from the sample, while not interfering with scattered X-rays at small angles from reaching the SAXS detector. A regular training program, the X9 workbench, has also been established to allow users to become familiar with beamline X9 for solution X-ray scattering.
近年来，人们对将 X 射线散射技术应用于溶液中的生物分子越来越感兴趣。在 NSLS，一条新的基于波荡器的光束线 X9 已经建成，以满足用户对 X 射线散射的过度需求。X9 光束线具有在单个仪器中进行小角/广角 X 射线散射（SAXS/WAXS）的能力。这是通过利用真空样品/探测器室来实现的，该室是 SAXS 散射飞行路径的一个组成部分。这个真空室允许 WAXS 探测器被放置在离样品很近的位置，同时不会干扰小角度散射的 X 射线到达 SAXS 探测器。一个定期的培训计划，X9 工作台，也已经建立，以允许用户熟悉用于溶液 X 射线散射的 X9 光束线。
