近年来，人们对X射线散射技术在溶液中生物分子的应用越来越感兴趣。在NSLS，一个新的波荡器为基础的光束线，X9，已建成，以解决超额认购的用户需求的X射线散射。Beamline X9能够在一台仪器中执行小/广角X射线散射（SAXS/WAXS）。这是通过利用真空样品/探测器室来实现的，该真空室是SAXS散射飞行路径的一个组成部分。该真空室允许WAXS探测器位于离样品很近的距离处，同时不会干扰以小角度到达SAXS探测器的散射X射线。还建立了一个定期培训计划，X9工作台，使用户能够熟悉用于解决X射线散射的光束线X9。
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.
