论文摘要
纵向相空间操纵是高级加速概念，辐射源和改善X射线游离电子激光器的性能的关键和必要组成部分。在这里，我们提出了一种简单且通用的方法，可以通过使用在量身定制的介电衬里的波导中生成的韦克菲尔德（Wakefields），半跑步构成带电束的纵向空间。我们将概念应用于模拟，并为辐射产生和束压缩提供示例。我们最终讨论了现代3D打印机的制造能力，并研究了印刷限制以及输入LP的形状如何影响设备的性能。
Longitudinal phase space manipulation is a critical and necessary component for advanced acceleration concepts, radiation sources and improving performances of X-ray free electron lasers. Here we present a simple and versatile method to semi-arbitrarily shape the longitudinal phase space of a charged bunch by using wakefields generated in tailored dielectric-lined waveguides. We apply the concept in simulation and provide examples for radiation generation and bunch compression. We finally discuss the manufacturing capabilities of a modern 3D printer and investigate how printing limitations, as well as the shape of the input LPS affect the performance of the device.
