This proposal requests support for a university-based Physics Accelerator Research and Development (R&D) program designed to address several opportunities in experimental free-electron lasers and high brightness beam physics. These opportunities have arisen from two sources: (1) the completion and upcoming commissioning of a magnetic chicane compressor built at UCLA for the Accelerator Test Facility (ATF) at BNL; and (2) the restart of the Visible to Infrared SASE Amplifier (VISA) self-amplified spontaneous emission free electron laser (SASE FEL) at the ATF. The proposed experimental program will allow this collaboration to investigate the physics of ultra-short electron beam production using chicane compression, and the generation of sub-picosecond (ps) radiation pulses from the SASE FEL process. These topics are at the frontier of beam physics today, and provide a rich context for university-based scholarly research. The proposed investigations are critical to the current development of 4th generation X-ray light sources which utilize SASE FELs, such as those at Stanford and DESY (Hamburg). In addition, they also impact high average power FELs, energy recovery linac (ERL) based light source systems, high energy physics linear colliders, and advanced (laser and plasma based) accelerators. These investigations are of critical importance to the development of the X-ray SASE FEL as the physical systems under test are shared: high brightness electron injector, sub-ps compressor, dogleg transport, and highly optimized undulator. The development of this comprehensive approach to address more sophisticated issues in high brightness beam-based radiation production will significantly aid in laying the scientific basis for the X-ray SASE FEL and other cutting edge accelerator systems.

该提案要求支持一项基于大学的物理加速器研究与开发（R D）计划，旨在解决实验自由电子激光器和高亮度束物理学中的多个机会。这些机会来自两个来源：（1）在加州大学洛杉矶分校为BNL的加速器测试设施（ATF）建造的磁减速压缩机的完成和即将投入使用;以及（2）ATF的可见光到红外SASE放大器（VISA）自放大自发辐射自由电子激光器（SASE FEL）的重新启动。 拟议的实验计划将允许这种合作，以调查超短电子束生产的物理使用弯道压缩，并从SASE自由电子激光过程中产生亚皮秒（ps）辐射脉冲。这些主题是当今束流物理学的前沿，为大学的学术研究提供了丰富的背景。 拟议的调查是至关重要的第四代X射线光源，利用SASE自由电子激光器，如那些在斯坦福大学和DESY（汉堡）的当前发展。此外，它们还影响高平均功率自由电子激光器、基于能量回收直线加速器（ERL）的光源系统、高能物理直线对撞机和先进（基于激光和等离子体）加速器。 这些调查是至关重要的X射线SASE自由电子激光的发展，作为测试下的物理系统共享：高亮度电子注入器，亚ps压缩机，狗腿运输，和高度优化的波荡器。这种解决高亮度束基辐射产生中更复杂问题的综合方法的发展将大大有助于为X射线SASE自由电子激光和其他尖端加速器系统奠定科学基础。
