摘要
FAST 光束线是计划中的伽马射线电子增强源（GREENS）计划的注入器，该计划旨在实现 515 nm 处高效率、高平均功率自由电子激光器的演示和首次应用。FAST-GREENS 要求高 5D 峰值亮度；横向归一化投射幅射为 3 mm-mrad，峰值电流为 600 A，这是 FEL 达到 10% 效率目标的最低光束要求。在这项工作中，将介绍为实现这些目标而对 FAST 光束线低能段进行的研究，包括对光束压缩和光束幅射的初步测量。此外，还介绍了为开发高保真模拟模型所做的努力，该模型可在以后针对 FAST-GREENS 进行优化。
FAST Low-Energy Beamline Studies: Toward High-Peak 5D Brightness Beams for FAST-GREENS
The FAST beamline is the injector for the planned Gamma-Ray Electron ENhanced Source (GREENS) program, which aims to achieve the demonstration and first application of a high-efficiency, high-average-power free-electron laser at 515 nm. FAST-GREENS requires high 5D peak brightness; transverse normalized projected emittances of 3 mm-mrad and a peak current of 600 A are the minimum beam requirements for the FEL to reach the 10% efficiency goal. In this work, studies of the low-energy section of the FAST beamline are presented toward these ends, including preliminary measurements of beam compression and beam emittance. An effort toward developing a high-fidelity simulation model that could be later optimized for FAST-GREENS is presented.
