Résumé

The possibility of accelerating electrons to the GeV level using a Petawatt laser focused in a uniform plasma is investigated. The proposed scheme relies on the wakefield acceleration of an electron bunch from a state-of-the-art radio frequency accelerator. Using an analytical model as well as numerical simulations performed withWAKE, an study of the injector parameters is carried out. In particular, it is found that the quality of the accelerated electron bunch -in terms of bunch length and energy spread- depends crucially on the injection energy. Injection energies of a few MeV lead to a GeV electron beam with sub-100 fs bunches and 10% energy spreads. Most of the features of the acceleration process can be explained with the analytical linear model, whom results are in good agreement with the numerical simulations.
