BEAMLINE COMMISSIONING & DETECTOR CHARACTERIZATION

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。 在每次运行开始时，我们通常需要2-3天的调试来表征和验证bemline的性能。这涉及以下任务：X射线束对准和转向（这涉及使波荡器光束沿着所定义的光束线参考点居中）、单色器对准、校准和聚焦（这涉及测量单色摇摆曲线、通过使用Au箔的能量校准和作为能量的函数的聚焦参数），垂直聚焦镜的校准和调试（这包括在不同配置下设置聚焦参数）、离子室线性测试和固态探测器调试。需要额外的调试时间（总共包括6个班次）来校准SAXS和光纤衍射应用的Avix和Brandeis面积探测器。该时间还包括从其他模态转换为SAXS或WAXS的设置时间（共包括12个班次）

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. At the beginning of each run we typically require 2-3 days of commissioning to characterize and verify the performance of the bemline. This involves the following tasks: x-ray beam alignment and steering (this involves centering the undulator beam along the defined beamline reference points), monochromator alignment, calibration and focusing (this involves measuring the monochromator rocking curve, energy calibration by using a Au foil and focusing parameters as a function of the energy), vertical focusing mirror alignment and commissioning (this includes setting the focusing parameters at different configurations), ion chamber linearity testing and solid state detectors commissioning. Additional commissioning time (6 shifts included in total) was required to calibrate the Aviex and Brandeis area detectors for SAXS and fiber diffraction applications. Also included in this time is setup time for changing to SAXS or WAXS from other modalities (12 shifts included in total)
