最近展示的激光制导技术已经成功地通过先进试验加速器和后加速器光束线传输了10kA相对论电子束95m。在先进试验加速器的端部，梁的最大横向位移为1 mm，最大梁破裂幅度为0.1 mm。激光导引的使用是加速器技术上的一大突破，因为它能够大大减少甚至抑制束流分裂不稳定性，而束流分裂不稳定性是直线感应加速器中强流束流传输的最大障碍。
The recently demonstrated technique of laser guiding has been used to propagate successfully a 10-kA relativistic electron beam 95 m through the Advanced Test Accelerator and postaccelerator beamline. The maximum transverse displacement of the beam at the end of the Advanced Test Accelerator was 1 mm while the maximum beam breakup amplitude was 0.1 mm. The use of laser guiding constitutes a breakthrough in accelerator technology in that it is able to reduce greatly or even suppress the beam breakup instability, which is the most serious obstacle to high-current beam transport in linear induction accelerators.
