Plasma optics improving plasma accelerators

摘要

Plasma accelerators driven by high-power lasers can provide high-energy electron beams on a dramatically smaller scale than conventional radio-frequency accelerators.However,the performance of these accelerators is fundamentally limited by the diffraction of the laser.Laser-generated plasma waveguides can mitigate this problem and,combined with a controlled injection method for electrons,highlight the potential of novel laser-plasma optics.
