Abstract

The Paul Scherrer Institute is implementing laser-based seeding in the soft X-ray beamline (Athos) of its free-electron laser, SwissFEL, to enhance the temporal and spectral properties of the delivered photon pulses. This technique requires, among other components, two identical modulators for coupling the electron beam with an external laser with a wavelength range between 260 and 1600 nm. The design, magnetic measurements results, alignment, operation and also details of the novel and exotic magnetic configuration of the prototype are described.

摘要

保罗谢勒研究所正在其自由电子激光瑞士光源的软 X 射线光束线（Athos）中实施基于激光的种子注入，以增强所传输的光子脉冲的时间和光谱特性。该技术除其他组件外，还需要两个相同的调制器，用于将电子束与波长范围在 260 至 1600nm 之间的外部激光耦合。本文介绍了原型的设计、磁测量结果、对准、操作以及新颖和奇特的磁配置的详细信息。
