Towards a compact X-ray free-electron laser based on laser-accelerated electron beams

In the presentation, we show the design and our approach to achieve soft X-ray free-electron lasers (FELs) by using staged laser plasma acceleration (LPA) of electrons.The staged LPA consists of several functionalized stages such as electron injector, phase rotation, and energy booster to manipulate electron beams to satisfy the requirements for an XFEL. This is a challenging task but this scheme has a favorable scaling to higher energies and has larger tuningknobs to manipulate electron beam quality.11th International Conference on Inertial Fusion Sciences and Application
