在等离子体中观察到了电子束的自调制现象。长（几个等离子体波长）电子聚束在过密等离子体中的传播导致了多个聚束的产生，通过自调制不稳定性。利用射频偏转器和偶极谱仪的组合，测量了自调制光束的时间和能量结构。纵向相空间测量显示了一个长的电子聚束成三个聚束的调制与约200 keV/c的幅度动量调制。证明这种效应是质子驱动等离子体加速器方案的一个突破，旨在利用相同的物理效应。
Self-modulation of an electron beam in a plasma has been observed. The propagation of a long (several plasma wavelengths) electron bunch in an overdense plasma resulted in the production of multiple bunches via the self-modulation instability. Using a combination of a radio-frequency deflector and a dipole spectrometer, the time and energy structure of the self-modulated beam was measured. The longitudinal phase space measurement showed the modulation of a long electron bunch into three bunches with an approximately 200 keV/c amplitude momentum modulation. Demonstrating this effect is a breakthrough for proton-driven plasma accelerator schemes aiming to utilize the same physical effect.
