OPERATIONAL STATUS OF 8-BM

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。8BM波束线是APS的第一个NE-CAT操作波束线。由于历史原因，它几乎位于我们24区主战场的中间地带。它的能量范围为6.5 ~ 14.0 KeV，能量分辨率为2 ~ 3ev。从APS弯曲磁源中获得1.2 mR辐射的风扇。2002年春天，第一个产生大分子结构的实验被收集起来。对光束线的不断改进使我们在2004年秋季向APS普通用户开放。此时我们的数据库已经启动，它正在持续使用，所有使用NE-CAT光束线的用户都被要求进入数据库。在过去的一年里，光束线容纳了35名独立调查员的45次访问。大多数小组来自学术机构，三个来自公司，另外三个来自结构基因组计划，一个来自晶体学学校。在8-BM上收集的数据导致2005历年出版了17份出版物。2005年初开始于用户操作，在秋季，专用于开发项目的波束时间略有增加，这导致2006年初几乎所有的时间都用于波束线升级。其他地方讨论的三个主要升级包括光学升级，Blu-Ice软件包的安装，以及先进光源（ALS）样品安装机器人的安装。在秋季学期开始时（2005年10月），我们开始调试blue - ice的实施。随后在11月的第二个星期安装了ALS自动安装机。最后，对双晶单色仪中的第一、二晶进行了升级。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The beamline 8BM was the first NE-CAT operational beamline at the APS. For historic reasons, it is located almost halfway around the ring from our main operations at Sector 24. It covers the energy range of 6.5 ¿ 14.0 KeV with an energy resolution of 2-3eV. A fan of 1.2 mR of radiation is taken from an APS bending magnet source. In the spring of 2002, the first experiment that produced a macromolecule structure was collected. Continuous refinement of the beamline led to our opening to APS general users in the fall of 2004. At this time our database was launched, it is in continuous use and all users to either of the NE-CAT beamlines have been required to enter the database. Over the past year, the beamline accommodated 45 visits from 35 independent investigators. The majority of the groups were from academic institutions, three were from companies, three others were structural genomics initiatives, and one was a crystallographic school. Data collected on 8-BM led to 17 publications in the calendar year 2005. The beginning of the year 2005 started in user operations, in the fall there was a slight increase in beamtime dedicated to development projects which lead to nearly all the time in early 2006 dedicated to beamline upgrades. The three major upgrades that are discussed elsewhere cover the optics upgrade, installation of the Blu-Ice software package, and installation of the Advanced Light Source (ALS) sample mounting robot. At the beginning of the fall trimester (October 2005), we began commissioning of the implementation of Blu-Ice. This was followed by the installation of the ALS automounter in the second week of November. Finally, the first and second crystals in the double crystal monochromator were upgraded.
