论文摘要
通过不足的血浆传播的强烈超短激光脉冲能够驱动相对论的等离子体波，从而产生具有极端梯度的加速结构。这些结构代表了一种新型的紧凑型来源，用于产生超偏远的超平梁。本章介绍了LWFA过程背后的理论背景。从电磁波的基本描述及其与颗粒的相互作用开始，提出了LWFA的主要方面。这些包括血浆波的激发，加速阶段的描述和注射机制。这些考虑是通过讨论对能量收益和扩展定律的基本限制的结论。
Intense ultrashort laser pulses propagating through an underdense plasma are able to drive relativistic plasma waves, creating accelerating structures with extreme gradients. These structures represent a new type of compact sources for generating ultrarelativistic, ultrashort electron beams. This chapter covers the theoretical background behind the process of LWFA. Starting from the basic description of electromagnetic waves and their interaction with particles, the main aspects of the LWFA are presented. These include the excitation of plasma waves, description of the acceleration phase and injection mechanisms. These considerations are concluded by a discussion of the fundamental limits on the energy gain and scaling laws.
