BEAMLINE SETUP AND DIAGNOSTICS

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。子项目及 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。 在每个运行周期开始时，我们设置光束线以实现最佳操作。 运行诊断以确保光束线的最高数据质量。这也是在运行周期中根据需要完成的。影响数据质量的因素，如快门主轴同步，光束聚焦，光束转向，光束的位置和色度稳定性，光束纯度（谐波抑制），能量校准，检测器响应和吞吐量，样品在低温流中的稳定性，数据传输，数据存储和计算基础设施进行诊断和调整，以实现最佳操作。样品低温冷却器的维修是为了无故障运行。

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 start of each run cycle we set up the beamline for optimum operation. Diagnostics are run to assure the highest data quality from our beamlines. This is also done during the run cycle as required. Factors affecting the data quality, such as shutter-spindle synchronization, beam focus, beam steering, positional and chromatic stability of the beam, beam purity (harmonic rejection), energy calibration, detector response and throughput, sample stability in the cryo-stream, data transfer, data storage and computational infrastructure are diagnosed and tuned for optimum operation. Sample cryocoolers are serviced for trouble-free functioning.
