BEAMLINE COMMISSIONING & DETECTOR CHARACTERIZATION

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。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。所列机构为中心，不一定是研究者所在机构。我们执行了标准光束线调试任务，以确保其性能：a）光束对准和转向，以使光束沿着光束线居中，B）使用校准的金属箔和EXAFS扫描进行单色仪校准，c）单色仪1和2性能测试（摇摆曲线、作为能量和距源的距离的函数的聚焦参数等），d）离子室测试e）使用离子室或BPM作为输入信号调谐单色反馈系统。f）镜调试程序（中心镜，作为样品距离的函数的聚焦参数，以及g） CCD测试和调试在APS环关闭后，每年执行三次此程序。当单色器或反射镜在关闭期间被修改或操纵时，进行更详细的调试。

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. We performed the standard beamline commissioning tasks to ensure its performance: a) beam alignment and steering to center the beam along the beamline, b) monochromator calibration using calibrated metal foils and EXAFS scans, c) monochromator 1 and 2 performance testing (rocking curve, focusing parameter as a function of the energy and distance from the source, and so on), d) ion chamber testing ( gas leaks, linearity), e) Tunning of the monochromator feedback system using ion chamber or BPM as input signal. f) Mirror commissioning procedure (center mirror, focusing parameter as a function of the sample distance, and g) CCD testing and commissioning This procedure is followed three times a year after the shut down period of the APS ring. More detailed commissioning is done when the monochromators or the mirror have been modified or manipulated during the shut down.
