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. Automated scripts were developed for 1) automated routine alignment of the x-ray beam to the phi axis, 2) alignment of the detector center to the direct beam and 3) calibration of the x-ray beam energy and sample to detector distance. Most of these tasks simply automate the tried and tested procedures used for manual alignment. However, a new procedure was developed for the phi axis alignment, involving the fluorescence scan of a thin (10 micron) W-Ni wire. The new alignment procedures have been implemented on all the SSRL macromolecular crystallography beam lines except on BL12-2, because the size of the fluorescence wire is the same size as the beam.

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。 开发了自动脚本，用于1）X射线束与phi轴的自动常规对准，2）探测器中心与直射光束的对准，以及3）X射线束能量和样本到探测器距离的校准。 这些任务中的大多数只是自动化用于手动对齐的久经考验的程序。然而，一种新的程序被开发用于phi轴对准，涉及细（10微米）W-Ni线的荧光扫描。 除了BL 12 -2外，所有SSRL大分子晶体学光束线都实施了新的对准程序，因为荧光线的尺寸与光束的尺寸相同。
