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. A new PILATUS 6M PAD system for macromolecular crystallography has been installed and commissioned. It was initially installed on BL9-1 for beam line integration. In collaboration with the vendor Dectris, the detector control and image file transfer were integrated into the standard SSRL beam line control system (Blu-Ice/DCS). Both shutter and ?shutterless? modes of data collection were developed. Comparison data sets were collected using a MAR325 CCD and the PAD which indicated similar or superior data processing statistics for the PAD data, exceeding the acceptance criteria. Once fully integrated and tested, the PAD was then installed on BL12-2 for further commissioning. During this period, the data collection parameters and the file transfer and data processing speeds were optimized. A new high-performance compute system was installed to support the PAD. The high-performance system is based on Hewlett Packard?s large-scale, high-speed and load balanced NAS/SAN file storage system and a scalable Blade CPU system based on Intel's latest Nehalem architecture. The detector/compute system was in user operation on BL12-2 for a significant fraction of the grant year.

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。 一个用于大分子晶体学的新的PILLENT 6 M PAD系统已经安装并投入使用。 它最初安装在BL 9 -1上用于光束线集成。 与供应商Dectris合作，将探测器控制和图像文件传输集成到标准SSRL束线控制系统（Blu-Ice/DCS）中。快门和？无快门？制定了数据收集模式。使用MAR 325 CCD和PAD收集比较数据集，表明PAD数据的数据处理统计相似或优于上级，超出验收标准。一旦完全集成和测试，PAD然后安装在BL 12 -2上进行进一步调试。在此期间，优化了数据收集参数以及文件传输和数据处理速度。 安装了一个新的高性能计算系统来支持PAD。 高性能的系统是基于惠普？的大规模、高速和负载平衡的NAS/SAN文件存储系统和基于英特尔最新Nehalem架构的可扩展刀片CPU系统。探测器/计算系统在BL 12 -2上的用户操作中占了拨款年度的很大一部分。
