Energy Recovery Linac (ERL) R&D 2-1-09 to 3-31-10

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。材料研究部的这一奖项支持康奈尔大学进行基于能量回收直线加速器(ERL)原理的超高光谱亮度硬X射线同步辐射源的加速器和X射线技术研发。ERL的高相干性和时间特性将对科学和工程产生广泛的影响，因为它使许多使用当前基于存储环的同步加速器源不可行的实验成为可能。ERL将在材料和生物结构的成像、无晶体晶体结构的大分子结构测定以及高压下物质、玻璃和无序材料以及多晶材料中的有效纳米级探测器方面产生革命性的影响。该研究计划涉及五个关键技术领域：(1)超导直线加速器的开发；(2)高亮度光注入器的开发；(3)高亮度电子束物理和诊断；(4)束动态效应；(5)开发ERL能力所需的X射线束线部件。技术研究和开发将与美国和国外的其他实验室合作进行。这项工作的一个主要成果包括培训学生和博士后研究员，以满足世界范围内对加速器物理和光束线科学家日益增长的需求，这些科学家熟悉新的高亮度同步加速器光束的机器和前端挑战。这项工作包括一个有效的、基于多样性的、广泛的面向K-12和本科生社区的外展计划。

0937466GrunerThis award is funded under the American Recovery and reinvestment Act of 2009 (Public Law 111-5). This award from Division of Materials Research supports Cornell University to perform accelerator and X-ray technology R&D for an ultrahigh spectral brightness, hard x-ray synchrotron radiation source based on the Energy Recovery Linac (ERL) principle. The high coherence and temporal properties of the ERL would have broad impact across the sciences and engineering by enabling numerous experiments that are not feasible using current storage ring based synchrotron sources. ERL will have transformative impact in imaging of materials and biological structures, macromolecular structure determination of crystal structure without crystals, and effective nano scale probes for matter at high pressures, in glasses and disordered materials, and polycrystalline materials. The research program addresses five critically important technology areas: (1) Superconducting linac development; (2) High brightness photoinjector development; (3) High brigthness electron beam physics and diagnostics; (4) Beam dynamic effects; and (5) X-ray beamline components necessary to exploit ERL capabilities will be developed. Technological research and development will be preformed in collaboration with other laboratories, both in the U.S. and abroad. A major product of this work includes the training of student and postdoctoral fellows to meet the growing world-wide demand for accelerator physics and beamline scientists familiar with the machines and front end challenges of new high brightness synchrotron beams. The work includes an effective, diversity-based, broad outreach program to the K-12 and undergraduate communities.
