Plasma accelerators can drastically shrink large-scale future accelerator facilities such as a linear collider. Maintaining high beam quality and accelerating with high energy efficiency is key to delivering high luminosity per wall-plug power. However, this is particularly challenging in a plasma accelerator due to their microscopic size—extreme precision and stability is required. We present recent results from DESY’s FLASHForward plasma-accelerator facility, showing preserved energy spread and charge while accelerating with GV/m gradients at record efficiency and stability. Moreover, a new concept for self-correcting plasma acceleration is presented, which may provide orders of magnitude better beam quality and stability for applications in the future.
