MICROPROBE DEVELOPMENT

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。 这些进展旨在改善BioCAT微探针的性能。安装了一个100微米的孔径来清理由KB反射镜产生的微光束。小孔安装在YX电动工作台上，这使得小孔在微束路径上的定位变得相当容易。该光圈还用作诊断微束位置变化的参考点。该孔径还使我们能够展示BioCAT光束线和微探针系统的高度稳定性。此外，还开发并实现了新的扫描软件BioCAT_FMAP。此版本使用HDF5格式保存映射数据。这种文件格式是为科学数据设计的，与常规的ASCII格式相比具有许多优点：压缩系数大，可以随机访问不同的字段。在这个新版本中修复了以前版本中的一些小错误。

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. These developments were directed towards improving the performance of the BioCAT microprobe. A 100 micron aperture was installed to clean up the microbeam generated by the KB mirrors. The aperture was mounted on an YX motorized stage that allows the positioning of the aperture on the microbeam path rather easily. The aperture also acts as a reference point for the diagnosis of position changes of the microbeam. The aperture also allowed us to demonstrate the high stability of the BioCAT beamline and microprobe system. In addition, new scanning software, BioCAT_FMAP, was developed and implemented. This version saves the mapping data using the HDF5 format. This file format was designed for scientific data and has many advantages over the regular ASCII format like: large compression factor, random access to different field. Some minor bugs from previous versions were fixed in this new version.
