Macromolecular Crystallography Activity at Beamline X9B

该科研究的目的是利用特别是在布鲁克海文国家实验室国家同步加速器光源的光束线X9B处产生的同步加速器存储环产生的X射线辐射的独特性质。同步辐射的两个最重要的特点是X射线的高强度和波长的可调性；在该科的研究调查中利用了这两个特点。 除了进行研究调查外，该科人员还为NIH研究人员在国家同步加速器光源的光束线X9B收集衍射数据提供技术和科学支持。NIH室内同步加速器大分子结晶仪联盟是参与研究团队的一部分，它使用了BEAMLINE X9B总可用时间的37.5%，相当于每四个月调度周期约25天。在同步加速器光束线上收集衍射数据涉及非常高的技术水平，但这是一个科学过程，而不是技术细节。因此，只有在科学考虑的基础上，才能适当地选择所有必要的参数。同步辐射研究科在衍射数据收集的所有方面为光束线X9B的用户提供支持。

The aim of the research within this Section is to utilize the unique properties of the X-ray radiation generated at synchrotron storage rings in particular, at beamline X9B of the National Synchrotron Light Source, Brookhaven National Laboratory. The two most important characteristics of synchrotron radiation are the high intensity of the X-ray beam and the tunability of the wavelength; both of these properties are utilized in the research investigations within the Section. In addition to conducting research investigations, the Section personnel provides technological and scientific support for NIH researchers collecting diffraction data at beamline X9B of the National Synchrotron Light Source. The NIH Intramural Synchrotron Consortium of macromolecular crystallographers is a part of the Participating Research Team and uses 37.5% of the total available time at beamline X9B, which is equivalent to about 25 days per four-month scheduling period. Collecting diffraction data at the synchrotron beamline involves a very high level of technology but it is a scientific process, not a technicality. Therefore, a proper selection of all the necessary parameters can be done only if based on scientific considerations. The Synchrotron Radiation Research Section supports the users of beamline X9B in all aspects of diffraction data collection.
