Stable Particle Acceleration in Coaxial Plasma Channels
Stable Particle Acceleration in Coaxial Plasma Channels
The attainable transformer ratio in plasma accelerators is limited by instabilities. Using three-dimensional particle-in-cell simulations, we demonstrate that these can be controlled using a hollow plasma channel with a co-axial plasma filament. The driver scatters electrons from the filament, and the slow pinch of the ions leads to a strong …
