FEL驱动双束流加速器纵向聚束分析
Analysis of longitudinal bunching inan FEL driven two-beam accelerator
摘要:
最近的实验[1]探索了使用自由电子激光(FEL)作为微波双束加速器的聚束器,以及随后的驻波射频输出腔的驱动。在这里,我们提出了一个更深入的分析的电子束团的纵向动力学,因为它们是从自由电子激光的末端,并通过输出腔传输。特别是,我们研究的效果的传输区域和腔孔过滤光束的聚束部分。[1]T. Lefevre,et.例如,物理修订信函84(2000),1188。
英文摘要:
Recent experiments [1] have explored the use of a free-electron laser (FEL) as a buncher for a microwave two-beam accelerator, and the subsequent driving of a standing-wave rf output cavity. Here we present a deeper analysis of the longitudinal dynamics of the electron bunches as they are transported from the end of the FEL and through the output cavity. In particular, we examine the effect of the transport region and cavity aperture to filter the bunched portion of the beam. [1] T. Lefevre, et. al., Phys. Rev. Lett. 84 (2000), 1188.
