OPERATIONAL STATUS OF 8-BM

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。波束线8BM是APS的第一条NE-CAT运行波束线。由于历史原因，它位于距离我们在24区的主要业务几乎一半的环。它的能量范围为6.5？14.0keV，能量分辨率为2-3 eV。从APS弯曲磁源获得1.2mR的辐射扇形。2002年春天，第一个产生大分子结构的实验被收集起来。光束线的不断改进使我们在2004年秋季向APS的普通用户开放。此时，我们的数据库已经启动，它仍在持续使用中，所有NE-CAT波束线的用户都被要求进入该数据库。在过去的一年里，光束线接待了35名独立调查人员的45次访问。大多数小组来自学术机构，三个来自公司，另外三个是结构基因组学倡议，一个是结晶学学校。收集的关于8-BM的数据导致2005年出版了17份出版物。2005年年初开始于用户运营，秋季专门用于开发项目的波束时间略有增加，这导致2006年初几乎所有时间都专门用于波束线升级。在其他地方讨论的三个主要升级包括光学系统升级、安装Blu-Ice软件包和安装高级光源(ALS)样本安装机器人。在秋季三个月初(2005年10月)，我们开始试行蓝冰的实施。紧随其后的是在11月的第二周安装ALS自动安装机。最后，对双晶单色仪中的第一和第二晶体进行了升级。

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.
