摘要

如果激光或粒子束驱动的等离子体汪场加速器在线性或中度非线性状态下运行，注入外部产生的待加速粒子束（见证粒子）可能会遇到对准问题。如果出现对准错误，阻尼器会扰动唤醒场，从而使验证体在轴上移动，而不会造成质量损失。

Oscillation damper for misaligned witness in plasma wakefield accelerator

If a laser- or particle beam-driven plasma wakefield accelerator operates in the linear or moderately nonlinear regime, injecting an externally produced particle bunch (witness) to be accelerated may encounter an alignment problem. Witness alignment tolerances can be relaxed by using a damper, an additional particle bunch produced by the same injector and propagating at a submillimeter distance ahead of the witness. If misaligned, the damper perturbs the wakefield in such a way that the witness shifts on-axis with no quality loss.
