Abstract Free-electron lasers generate high-brilliance coherent radiation at wavelengths spanning from the infrared to X-ray domains. The recent development of short-wavelength seeded free-electron now allows for unprecedented levels control on longitudinal coherence, opening new scientific avenues such as ultra-fast dynamics complex systems and nonlinear optics. Although those devices rely sta...

Energy-efficient plasma-wakefield acceleration of particle bunches with low energy spread is a promising path to realizing compact free-electron lasers and colliders. High efficiency can be achieved simultaneously by strong beam loading plasma wakefields when accelerating carefully tailored current profiles [M. Tzoufras et al., Phys. Rev. Lett. 101, 145002 (2008)]. We experimentally demonstrate...

A classical model of radiation reaction for the betatron oscillation an electron in a plasma wakefield accelerator is presented. The maximum energy due to longitudinal found, and damping both transverse effects analyzed. Both theoretical numerical solutions are shown with good agreements. regime that quantum takes effect also discussed. This important designing future based super accelerators o...
