Particle Injection into the Wave Acceleration Phase due to Nonlinear Wake Wave-Breaking

摘要

The wake wave-break that occurs due to the inhomogeneity of the Langmuir frequency in an inhomogeneous plasma makes it possible to inject electrons into the acceleration phase of the wave. Particle in cell simulations show that stable beams of energetic electrons are formed. These beams are well bunched in coordinate and velocity space and contain a considerable fraction of the pulse energy.
