DESCRIPTION (provided by applicant): Intense x-rays from Synchrotron Radiation sources are having an increasingly revolutionary impact on science and technology, and in particular, macromolecular crystallography. Recent research at Stanford University has led to a new x-ray source that will have a major impact on protein structure determination for health care. The Compact Light Source (CLS) is a breakthrough technology that offers a tunable, tabletop x-ray source that could be used like an x-ray beamline at a large light source. The compact size is achieved through the marriage of a laser and a miniature electron storage ring. The photon flux on a sample will be comparable to many synchrotron beamlines. The overall goals of this proposal are to first engineer, then prototype, and finally demonstrate the performance of the CLS. In Phase I, we will test the laser system and design the electron storage ring. In Phase II, we will build the storage ring, integrate the laser system, and demonstrate x-ray production. The CLS will also provide the foundation for future x-ray applications in the health care field. With the CLS, clinical applications such as non-invasive coronary angiography, diffraction-enhanced imaging, and improved cancer detection could be moved from the laboratory into hospitals throughout the nation.

描述(申请人提供)：来自同步辐射光源的强X射线正在对科学和技术产生日益革命性的影响，特别是在大分子结晶学方面。斯坦福大学最近的研究导致了一种新的X射线源，它将对医疗保健中的蛋白质结构测定产生重大影响。紧凑型光源(CLS)是一项突破性技术，它提供了一种可调的桌面X射线源，可以像大光源上的X射线光束线一样使用。紧凑的尺寸是通过激光器和微型电子存储环的结合实现的。样品上的光子通量将可与许多同步加速器光束线相媲美。该方案的总体目标是首先进行工程设计，然后进行原型设计，最后展示CLS的性能。在第一阶段，我们将测试激光系统并设计电子存储环。在第二阶段，我们将建造存储环，集成激光系统，并演示X射线产生。CLS还将为未来X射线在医疗保健领域的应用奠定基础。有了CLS，临床应用，如非侵入性冠状动脉造影、衍射增强成像和改进的癌症检测，可以从实验室转移到全国各地的医院。
