Advances in lasers and particles accelerators are opening new research avenues in the exploration of strong-field quantum electrodynamics processes. In addition to their fundamental and astrophysical interest, these processes can be leveraged to design new gamma ray sources with unprecedented brightness. This is the aim of the ANR g4QED project, which brings together physicists from the Laboratoire pour l’Utilisation des Lasers Intenses (LULI), the Laboratoire d’Optique Appliquée (LOA) and the LMCE. Experiments carried out on the Apollon laser and the FACET-II accelarator at SLAC (Stanford) will seek to optimize radiative processes via various interaction schemes, and to validate the simulation tools developed within the collaboration. We will consider the interaction of an ultra-intense laser pulse with a foam, the Compton collision of an ultra-intense laser pulse with an ultra-relativistic electron beam accelerator by a laser-plasma accelerator, and the interaction of an ultra-relativistic electron beam with a multi-foil target.
