Simulation of electron postacceleration in a two-stage laser wakefield accelerator

Simulation of electron postacceleration in a two-stage laser wakefield accelerator

Electron bunches produced in self-modulated laser wakefield experiments usually have a broad energy distribution, with most electrons at low energy (1–3 MeV) and only a small fraction at high energy. We propose and investigate further acceleration of such bunches in a channel-guided resonant laser w...
