标题： Generation of Multi-Color Attosecond X-Ray Radiation Through Modulation Compression

摘要： 在本文中，我们提出一种方案，以生成可调多色飞秒相干X射线辐射，用于未来光源应用。 该方案使用能量啁啾电子束、激光调制器、激光啁啾器和两个束压缩器，从直线加速器输出的几安培电子束生成多尖峰预聚束千安电流电子束。 这种电子束通过一系列波荡器辐射器和束压缩器，生成多色相干X射线辐射。 作为说明，我们提供一个示例，使用 $30$ 安培 $200$ 纳米激光种子电子束生成两个具有 $2.2$ 纳米和 $3$ 纳米相干X射线辐射波长且峰值功率超过 $200$ 兆瓦的飞秒脉冲。 显示英文摘要

摘要： In this paper, we propose a scheme to generate tunable multi-color attosecond coherent X-ray radiation for future light source applications. This scheme uses an energy chirped electron beam, a laser modulators, a laser chirper and two bunch compressors to generate a multi-spike prebunched kilo-Ampere current electron beam from a few tens Ampere electron beam out of a linac. Such an electron beam transports through a series of undulator radiators and bunch compressors to generate multi-color coherent X-ray radiation. As an illustration, we present an example to generate two attosecond pulses with $2.2$ nm and $3$ nm coherent X-ray radiation wavelength and more than $200$ MW peak power using a $30$ Ampere $200$ nm laser seeded electron beam.
