摘要:
Particle simulations of the modified two‐stream instability demonstrate strong electron acceleration rather than bulk heating when the relative drift speedvdis below a critical speedVc. A very interesting nonlinear autoresonance acceleration process is observed which accelerates the electrons much above the phase speed of the linearly unstable modes. Simple criteria are presented that predict the value ofVcand the number density of the accelerated electrons.
