BEAMLINE SETUP AND DIAGNOSTICS

这个子项目是利用资源的许多研究子项目之一。 由NIH/NCRR资助的中心拨款提供。对子项目的主要支持 子项目的首席调查员可能是由其他来源提供的， 包括美国国立卫生研究院的其他来源。为子项目列出的总成本可能 表示该子项目使用的中心基础设施的估计数量， 不是由NCRR赠款提供给次级项目或次级项目工作人员的直接资金。 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。样品冷冻机进行维修，以确保无故障运行。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. At the start of each run cycle, we setup the beamline for optimum operation. Diagnostics are run to assure 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 cryo-coolers are serviced for trouble-free functioning.
