BEAMLINE SETUP AND DIAGNOSTICS

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。 在每个运行周期开始时，我们设置最佳运行的光束线。运行诊断以确保来自我们的光束线的最高数据质量。这也是在运行周期内根据需要完成的。对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、探测器响应和吞吐量、低温流中的样品稳定性、数据传输、数据存储和计算基础设施进行了诊断和调整，以实现最佳操作。为确保无故障运行，对样品冷冻机进行了维修。

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.
