简要介绍了一种将激光韦克菲尔德加速器产生的电子束团注入质子驱动等离子体韦克菲尔德加速器的方案。该聚束可以很短（fs），携带高电流（kA），并且可以理想地加载由自调制聚束驱动的尾流场，从而产生具有窄最终能量扩展的加速聚束。在AWAKE实验中，注入的聚束也与尾场的种子固有地同步。
We briefly describe a scheme in which an electron bunch produced by a laser wakefield accelerator is injected in a proton-driven plasma wakefield accelerator. This bunch can be short (fs), carry high current (kA) and could be ideal to load the wakefields driven by a self-modulated bunch and thereby produce an accelerated bunch with narrow final energy spread. In the AWAKE experiment the injected bunch is also inherently synchronized with the seed of the wakefields.
