Observation of monoenergetic electrons from two-pulse ionization injection in quasilinear laser-wakefields
The generation of low emittance electron beams from laser-driven wakefields is crucial for the development of compact X-ray sources. Here, we show new results for the injection and acceleration of quasi-monoenergetic electron beams in low amplitude wakefields experimentally and using simulations. Th...

| description | The generation of low emittance electron beams from laser-driven wakefields is crucial for the
development of compact X-ray sources. Here, we show new results for the injection and acceleration of quasi-monoenergetic electron beams in low amplitude wakefields experimentally and using
simulations. This is achieved by using two laser pulses decoupling the wakefield generation from the
electron trapping via ionization injection. The injection duration, which affects the beam charge and
energy spread, is found to be tunable by adjusting the relative pulse delay. By changing the polarization of the injector pulse, reducing the ionization volume, the electron spectra of the accelerated
electron bunches are improved. |
