Overcoming the dephasing limit in multiple-pulse laser wakefield acceleration
Overcoming the dephasing limit in multiple-pulse laser wakefield acceleration
The electric field in laser-driven plasma wakefield acceleration is orders of magnitude higher than conventional radio-frequency cavities, but the energy gain is limited by dephasing between the ultra-relativistic electron bunch and the wakefield, which travels at the laser group velocity. We present a way to overcome this limit within a …
