FOCUSING DEVELOPMENT

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 研究中心，而研究中心不一定是研究者所在的机构。 一天的光束时间专门用于优化光束线垂直聚焦镜的参数。研究发现水平聚焦对垂直聚焦有影响，因此我们研究了不同的水平聚焦配置，以找到垂直镜面聚焦的最佳条件。我们观察到，通过选择适当的水平聚焦参数，如扭曲和焦点，可以提高垂直光束的大小。我们还研究了垂直参数的不同组合，考虑到有16个参数可用。该测试期间实现的最佳聚焦为50微米FWHM。这个光束尺寸对于我们目前正在进行的实验来说是足够的。将需要额外的硬件组件和工作来将该光束尺寸减小到30微米，因为这是该设备的预期最佳性能。

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. One day of beamtime was devoted to optimize the parameters of the beamline vertical focusing mirror. It's been found that the horizontal focusing affects the vertical focusing; therefore we investigated different horizontal focusing configurations to find optimum conditions for vertical mirror focusing. We observed that the vertical beam size can be improved by selecting the appropriate horizontal focusing parameters such as twist and focus. We also investigated different combinations of the vertical parameter, considering there are 16 parameters available. The best focus achieved during this test was 50 micron FWHM. This beam size showed to be sufficient for the kind of experiment we are performing up to now. Additional hardware components and effort will be required to reduce this beam size down to 30 microns as this is the expected optimum performance of this device.
