Decoupling acceleration and wiggling in a laser-produced Betatron source
Julien Gautier, Igor Andriyash, Andreas Döpp +11
Betatron radiation is produced in Laser Plasma Accelerators when the electrons are accelerated and simultaneously wiggle across the propagation axis. The mechanisms of electron acc…
Empirical scaling laws for self-focused laser pulses in nitrogen plasmas
Lorenzo Martelli, Igor Andriyash, Jonathan Wheeler +3
We investigate the interaction between a superintense laser pulse and a nitrogen plasma with densities exceeding cm, using particle-in-cell simulations. Such conf…
Quasi-monoenergetic multi-GeV electron acceleration in a plasma waveguide
Ronan Lahaye, Kosta Oubrerie, Olena Kononenko +3
Laser-plasma accelerators present a promising alternative to conventional accelerators. To fully exploit the extreme amplitudes of the plasma fields and produce high-quality beams,…
Compton photons at the GeV scale from self-aligned collisions with a plasma mirror
Aimé Matheron, Jean-Raphaël Marquès, Vincent Lelasseux +34
With today's multi-petawatt lasers, testing quantum electrodynamics (QED) in the strong field regime, where the electric field exceeds the Schwinger critical field in the rest fram…
