METHOD OF TRAPPING AND ACCELERATING OF BACKGROUND PLASMA ELECTRONS IN A PLASMA WAKEFIELD USING A DENSITY TRANSITION

摘要

The present invention by, the background plasma electrons plasma wake field (航跡 場; wake field) by using the density reduced the transition to a method for accelerating the take on. According to the present invention accelerates the strong laser pulse or a short electron beam by passing the low-density plasma having a rapid density reduction transition pulse capturing the plasma electrons in the background without any external injection for acceleration electron itself, in which the scale of the density transition length It is much shorter than the wavelength of the plasma wake wave. Characteristics of the density reduction transition is to produce by applying a laser pulse having an intensity of stairs lateral vertically. When the plasma wake wave to pass through the transition density, the wavelength is suddenly increased to accelerate some of the background plasma electrons are injected into the acceleration phase of the wave being trapped in the wakes strong plasma wave trajectory.
