This is a challenging task but this scheme has a favorable scaling to higher energies and has larger tuning knobs to manipulate electron beam quality., 11th International Conference on Inertial Fusion Sciences and Applications}, title = {Towards a compact X-ray free-electron laser based on laser-accelerated electron beams}, year = {2019} }
