X-ray Free-Electron Laser: Marvelous Light Created by Particle Accelerator
Large scientific facilities driven by relativistic electron beams, such as synchrotron light sources, have played a key role in the development of physics, chemistry, biology, and material science. These massive machines produce intense x-rays that researchers use to probe molecules, atoms, crystals, and innovative new materials in order to better understand their structure and behavior. In this talk, I will give an overview of recent advances in the development of x-ray light sources. I will focus on x-ray free-electron lasers that are enabling forefront science in various areas by giving researchers unparalleled power and precision in examining the fundamental nature of matter.
向导，2008年毕业于清华大学工程物理系，获博士学位；随后作为助理研究员（Research Associate）赴斯坦福大学SLAC国家加速器实验室（原斯坦福直线加速器中心）从事加速器物理和自由电子激光领域的相关研究。期间在回声激发谐波放大自由电子激光（Echo-Enabled Harmonic Generation Free-Electron Laser）领域进行了开创性的研究，作为首席科学家主持了逾500万美元的相关原理验证性项目，于2010年跳过副研究员（Associate Staff Scientist）破格晋升为研究员（Staff Scientist）。目前已发表70余篇文章，其中1篇发表在Nature Physics，7篇发表在Phys. Rev. Lett. (其中5篇为第一或通讯作者)。目前作为项目负责人（Principal Investigator）主持下一代自由电子激光先进束流操控和先进运行模式的研究，2012年获得美国能源部杰出青年科学家奖（DOE Early Career Award），2013年获得自由电子激光青年科学家奖（Young Investigator Free-Electron Laser Prize）。
