APOLLON laser facility was initiated by Nobel Laureat Gérard Mourou to become one of the few European 10 PW laser facilities. End of 2018, APOLLON reached 1 PW peak power. Experiments at this power are under preparation with an expected start during spring 2019 or early summer. In parallel, today the laser is under upgrade for reaching 10 PW in few years with an intermediate step at around 5 PW dedicated to the development of experiments at this high power. APOLLON will be open for external users on 2020 at 1 PW and very likely on 2021 at several PW. APOLLON has two experimental areas on which X-ray sources will be developed. The so-called "Long focal length area" (LFA) is dedicated to electron acceleration and related X-ray emission. The room may accommodate focal length up to 9m. The experiments are designed in a way to allows single or double stage electron acceleration with expected electron energies reaching several 10's of GeV. X-ray emission from betatron will be used as a diagnostic of electron acceleration processes but will be also developed independently aiming at achieving energetic and well-collimated X-ray beam. The experiment has been set in a way to allows heads-on electron-laser collision for Compton scattering experiments. The second target area called "Short Focal area", aims at achieving intensities as high as possible for electron and ion acceleration, non-linear QED tests and X-ray generation through high harmonic generation on solid. X-ray emission ranging up to 10 keV is foreseen, with very high peak power at lower energy.
