COMMISSIONING AND OPERATIONAL STATUS OF THE UNDULATOR BEAMLINES

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。次级项目的主要支助 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 为子项目列出的总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 在整个报告期内，NE-CAT波荡器光束线在使用饱和或接近使用饱和的情况下成功运行。 电子束线波束转向系统被重新配置以允许连续的数据收集（在先前的方案下，为了波束转向，数据收集被周期性地中断）。 开发了新的方法用于测定射束位置和稳定性，使用MD 2主轴轴处的X射线射束的视频图像（用BGO荧光桅杆采集）和控制台图像分析服务器，并与通过射束位置监视器获得的射束位置测量值进行比较。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. The NE-CAT undulator beamlines operated successfully throughout the entire reporting period at or near use saturation. The E-beam line beam steering system was reconfigured to permit continuous data collection (under the prior scheme data collection was interrupted periodically for the sake of beam steering). New methods were developed for assaying beam position and stability, using video images of the x-ray beam at the MD2 spindle axis (acquired with the BGO fluorescence mast) and the Console Image Analysis server and compared to beam position measurements obtained via the beam position monitors.
