我们提供了一种途径，紧凑的超亮光源，超亮，高能量的电子束出现的等离子体韦克菲尔德加速和等离子体光电阴极的组合的基础上。虽然已知等离子体加速产生比常规加速器大三个或四个数量级的加速场，但等离子体光阴极允许产生比常规加速器亮三个或四个数量级的电子束，并且因此适合于释放等离子体加速器的全部潜力。特别地，这是各种类型的光源的情况，其极大地受益于增加的电子束亮度。在最近的第一个实验演示的等离子体光电阴极的基础上，在这项工作中，我们讨论了等离子体光电阴极的前景，如X射线自由电子激光器，电子感应加速器辐射，离子通道激光器和逆康普顿散射的关键光子源的方法。
We provide a pathway to compact ultrabright light sources, based on ultrabright, high energy electron beams emerging from a combination of plasma Wakefield acceleration and plasma photocathodes. While plasma acceleration is known to produce accelerating fields three or four orders of magnitude larger than conventional accelerators, the plasma photocathode allows production of electron beams three or four orders of magnitude brighter than conventional, and thus is suitable to unleash the full potential of plasma accelerators. In particular, this is the case for various types of light sources, which profit enormously from an increased electron beam brightness. Building on the recent first experimental demonstration of the plasma photocathode, in this work we discuss the prospects of plasma photocathodes for key photon source approaches such as x-ray free-electron lasers, betatron radiation, ion-channel lasers and inverse Compton scattering.
