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.

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 用于大分子结晶学的新的Pilatus 6M PAD系统已经安装并投入使用。它最初安装在BL9-1上，用于束线集成。在与供应商Dectris的合作下，探测器控制和图像文件传输被集成到标准SSRL光束线控制系统(BLU-ICE/DCS)中。快门和无快门？开发了数据收集模式。使用MAR325 CCD和PAD收集比较数据集，该PAD表示PAD数据的相似或更好的数据处理统计，超出验收标准。一旦完全集成和测试，该垫随后被安装在BL12-2上进行进一步的调试。在此期间，对数据采集参数以及文件传输和数据处理速度进行了优化。安装了一个新的高性能计算系统来支持PAD。高性能系统基于惠普S大规模、高速、负载均衡的NAS/SAN文件存储系统和基于英特尔最新Nehalem架构的可扩展刀片式CPU系统。在赠款年度的很大一部分时间里，探测器/计算机系统在BL12-2上处于用户操作状态。
