等离子体中的种子自调制可以将长质子束转换成一系列微聚束，这些微聚束可以在长距离上激发强韦克菲尔德，但这需要等离子体具有一定的密度分布和短尺度的斜升。对于在欧洲核子研究中心的AWAKE实验的参数，我们数值研究的密度分布是最佳的，如果自调制种子由一个短的电子束。利用最佳剖面，可以将韦克菲尔德“冻结”在大约一半的破波水平。高能电子聚束（160 MeV）比低能电子聚束（18 MeV）的种子效率低，因为前者的韦克菲尔德持续的时间比有效播种所需的时间长。
Seeded self-modulation in a plasma can transform a long proton beam into a train of micro-bunches that can excite a strong wakefield over long distances, but this needs the plasma to have a certain density profile with a short-scale ramp up. For the parameters of the AWAKE experiment at CERN we numerically study which density profiles are optimal if the self-modulation is seeded by a short electron bunch. With the optimal profiles, it is possible to ‘freeze’ the wakefield at approximately half the wavebreaking level. High-energy electron bunches (160 MeV) are less efficient seeds than low-energy ones (18 MeV), because the wakefield of the former lasts longer than necessary for efficient seeding.
