This Expedited Award for Novel Research is an extension of work previously supported under NSF grant ECS-8611875. Under the previous grant research, Professor Byer and his group have made major advances in development of a tabletop-sized scanning soft x-ray microscope using a laser-produced plasma as the source of intense X-rays. This approach to a scanning soft x-ray microscope is currently the only such one which does not require a major synchrotron light source facility as the radiation source. Professor Byer has proposed a novel utilization of this new microscope capability to demonstrate x-ray transmission tomography of small samples at 140A wavelength. The various techniques of computer tomography currently employed for 3- dimensional imaging have already had major impact on fields such as medicine, biology, and materials research. This project could provide a significant new research capability in these areas and would be the first demonstration of soft x-ray tomography.

这一创新研究快速奖是先前由美国国家科学基金会资助的ECS-8611875资助工作的延伸。在之前的拨款研究中，拜尔教授和他的团队在开发桌面大小的扫描软X射线显微镜方面取得了重大进展，该显微镜使用激光产生的等离子体作为强X射线的来源。这种扫描软X射线显微镜的方法是目前唯一一种不需要主要的同步辐射光源设施作为辐射源的方法。拜尔教授提出了一种新的利用这种新的显微镜能力来演示140a波长下小样本的X射线透射层析成像的方法。目前用于三维成像的各种计算机层析成像技术已经对医学、生物和材料研究等领域产生了重大影响。该项目可以在这些领域提供重要的新的研究能力，并将是软X射线层析成像的第一个示范。
