BEAMLINE COMMISSIONING & DETECTOR CHARACTERIZATION

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 在每次运行开始时，我们通常需要2-3天的调试时间来表征和验证bemline的性能。这涉及以下任务：X射线光束对准和转向(其中涉及将波动光束沿所定义的光束线参考点对中)、单色器对准、校准和聚焦(其中涉及测量单色器摇摆曲线、使用金箔进行能量校准和聚焦参数作为能量的函数)、垂直聚焦镜对准和调试(其中包括在不同配置下设置聚焦参数)、电离室线性测试和固态探测器调试。为了校准SAXS和光纤衍射应用中的Aviex和Brandeis区域探测器，需要额外的调试时间(总共包括6个班次)。此时间还包括从其他医疗设备更改为SAXS或WAXS的设置时间(总共包括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)
