Injection of a relativistic electron beam into a high intensity optical lattice
Résumé
We present a numerical study of the injection and trapping process of a bunch of relativistic free electrons into a transverse high intensity optical lattice. We unravel different injection regimes depending on the characteristic length scale of the onset of the optical lattice , and explore how the characteristics of the electron beam and of the high intensity lattice affect the trapping rate. The average transverse kinetic energy , and the induced longitudinal energy broadening are studied. The analysis of the transverse phase space exhibits a complex behavior , leading to inhomogeneities that may affect the amplification dynamics of X-ray Free Electron Laser .
