COMMISSIONING OF BL12-2 ? A NEW HIGH-BRIGHTNESS MACROMOLECULAR CRYSTALLOGRAPHY B

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 光束线12-2是一种新型的、基于真空波荡器的、高亮度的、最先进的大分子晶体学光束线，它针对微晶、弱衍射系统（如膜和大型复合物）的研究以及其他要求苛刻的科学项目进行了优化。 光束线是由戈登和贝蒂摩尔基金会在加州理工学院和SSRL之间的合作礼物资助的，并将提供60%的一般用户访问。 作为光束线调试的一部分，对光束进行了表征，并测量了光学器件的稳定性。 一个新的俯仰反馈监控器的实施，以稳定梁。 安装并测试了厨房基础设施。 测试数据由加州理工学院的工作人员和委托用户组收集，他们也从样本中收集了测试数据集。

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. Beam Line 12-2 is a new, in-vacuum undulator based, high-brightness, state-of-the-art macromolecular crystallography beam line that is optimized for the study of microcrystals, weakly diffracting systems such as membranes and large complexes, and for other demanding scientific projects. The beam line was funded by a gift from the Gordon and Betty Moore Foundation in a collaboration between the California Institute of Technology and SSRL, and will provide 60% general user access. As part of the beam line commissioning, the beam was characterized and the stability of the optics were measured. A new pitch feedback monitor was implemented to stabilize the beam. The hutch infrastructure was installed and tested. Test data were collected by staff and commissioning user groups from Caltech also collected test data sets from their samples.
