Development of an Ultrafast X-Ray Scattering Facility at the Advanced Light Source

9601496将在劳伦斯伯克利实验室高级光源的同步加速器光束线上开发一种亚皮秒X射线散射设备。这是加州大学伯克利分校、密歇根大学和劳伦斯·伯克利实验室共同努力的成果。该设施在X射线光束线上安装了一台超快X射线条纹相机。然后，这个快速探测器将被用来研究来自有序材料的快速演变的X射线衍射图，这些有序材料受到超短脉冲激光能量的脉冲扰动。熔化和其他结构相变的动力学将以这种方式进行探索。%这项研究将产生一种独特的设备，用于通过X射线散射对结构相变进行超快研究。该设施满足了同步加速器技术在短时间内进行实时研究的当前需求。X射线条纹相机的开发具有将该技术转移到商业部门的潜力。***

9601496 Falcone A sub-picosecond x-ray scattering facility will be developed at a synchrotron beamline at the Advanced Light Source at Lawrence Berkeley Laboratory. This is a collaborative effort between the University of California at Berkeley, the University of Michigan, and Lawrence Berkeley Laboratory. The facility incorporates an ultrafast x-ray streak camera on the x-ray beamline. This fast detector will then be used to study rapidly evolving x-ray diffraction patterns from ordered materials that are impulsively perturbed by energy from an ultrashort pulse laser. The dynamics of melting and other structural phase transitions will be probed in this way. %%% The research will result in a unique facility for ultrafast studies of structural phase transitions by x-ray scattering. The facility fills a current need at synchrotron sources of techniques for carrying out real-time studies in a short time scale. The x-ray streak camera development has potential for transferring the technology to the commercial sector. ***
