IMR: Phase Ib Energy Recovery Linac (ERL) Technology R&D

这份来自材料研究部和化学部的奖励支持康奈尔大学进行加速器和x射线技术研究与开发（R&amp；D），以非特定地点的方式推进超高光谱亮度，硬x射线相干光源（CLS）的建设准备，如能量回收直线加速器和x射线自由电子激光器。CLS的高相干性和时间特性将改变科学和工程，并使使用现有x射线源无法进行的许多实验成为可能。启用的能力将包括研究超快化学反应，材料和生物结构的全息成像，确定蛋白质结构的新方法，极高压力下物质的性质，以及玻璃，无序和多晶材料的性质。实现CLS所需的电子束和x射线技术需要持续的研发。康奈尔大学建议利用以前NSF奖励下组装的设备进行基于能量回收直线加速器技术的研发，特别强调必要的(1)超导电子加速器，(2)电子源，(3)电子束物理和诊断，(4)电子束动力学，以及(5)能够处理CLS x射线束的x射线束线组件。研发将涉及与美国和国外其他实验室的合作。培训技术劳动力将是这项工作的主要成果。由于世界范围内对熟悉新的高亮度同步加速器光束的设备和挑战的加速器物理学家和光束线科学家的强烈需求，这种培训变得更加重要。这项工作包括一个有效的、基于多样性的、面向K-12和本科社区的广泛推广计划。

0807731 Gruner This award from the Division of Materials Research and the Division of Chemistry supports Cornell University to perform accelerator and x-ray technology research and development (R&D) to advance in a non-site specific way preparation for construction of an ultrahigh spectral brightness, hard x-ray coherent light sources (CLS), such as Energy Recovery Linacs and X-ray Free Electron Lasers. The high coherence and temporal properties of a CLS would transform the sciences and engineering and would enable numerous experiments that are not feasible using existing x-ray sources. Enabled capabilities would include studies on ultrafast chemical reactions, holographic imaging of materials and biological structures, new ways to determine the structure of proteins, properties of matter under extremely high pressures, and properties of glasses, disordered, and polycrystalline materials. Continued R&D is needed on the electron beam and x-ray technologies required to realize a CLS. Cornell proposes to utilize apparatus assembled under previous NSF awards to perform R&D based on the Energy Recovery Linac Technology, with specific emphasis on the requisite (1) superconducting electron accelerators, (2) electron sources, (3) electron beam physics and diagnostics, (4) electron beam dynamics, and (5) x-ray beamline components capable of handling CLS x-ray beams. The R&D will involve collaborations with other laboratories, both in the U.S. and abroad. Training the technical work force will be a major product of the work. This training is made more important by intense world-wide demand for accelerator physicists and beamline scientists familiar with the apparatus and challenges of new high brightness synchrotron beams. The work includes an effective, diversity-based, broad outreach program to the K-12 and undergraduate communities.
