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. We have modified the Console beam line, MD2 microdiffractometer and ADSC Q315 detector control systems to greatly simplify the working environments and add new functionality to of both of our undulator beam lines. Control authority for sample alignment and programming of data collection has been transferred from the MD2 and ADSC control systems (respectively) to the Auxiliary Console script of both the C- and E-beamline. This was accomplished by major reworking of all three control systems and adding new functionalities to Console. Users will now only have to interact with one unified Graphical User Interface to program all phases of crystallographic data collection. Console scripting for automatic XAFS spectra acquisition on the E-beam line was developed for facile energy calibration. We developed new scanned data collection methods and image-analysis driven Console scripting for rapid, accurate sample loop alignment (<10 sec) and automatic kappa axis alignments, driven by the STAC kappa axis data strategry prediction program. The Console control system has been modified to permit remote access control of the beamline. This new functionality is gained without any modification to existing Console scripting source code base. Preparations are underway for installation of the Dectris Pilatus 6M PAD detector. Modifications of the C-line monochromator intended to improve short term vertical beam stability and a method for facile conversion between the ADSC Q315 and Pilatus 6M detectors are presented.

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。子项目的主要支持 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。 列出的子项目总成本可能 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。 我们对控制台光束线、MD 2微衍射仪和ADSC Q315探测器控制系统进行了改进，大大简化了工作环境，并为我们的两条波荡器光束线增加了新功能。 样品校准和数据采集编程的控制权限已从MD 2和ADSC控制系统（分别）转移到C-和E-光束线的辅助控制台脚本。 这是通过对所有三个控制系统进行重大改造并在控制台上增加新功能来实现的。 用户现在只需要与一个统一的图形用户界面进行交互，即可对晶体学数据收集的所有阶段进行编程。 控制台脚本的自动XAFS光谱采集电子束线上开发了简便的能量校准。 我们开发了新的扫描数据收集方法和图像分析驱动的控制台脚本，用于快速、准确的样品环对齐（<10秒）和自动kappa轴对齐，由STAC kappa轴数据策略预测程序驱动。 控制台控制系统已被修改，以允许远程访问控制光束线。 此新功能无需对现有控制台脚本源代码库进行任何修改即可获得。 Dectris Pilatus 6 M PAD探测器的安装准备工作正在进行中。 本文介绍了对C线单色器进行改进以提高垂直束流的短期稳定性，以及在ADSC Q315和Pilatus 6 M探测器之间进行简单转换的方法。
