Plasma wakefield accelerators can be driven either by intense laser pulses (LWFA) or by
intense particle beams (PWFA). A third approach that combines the complementary …

We present a high-energy laser source consisting of an ultrafast thin-disk amplifier followed
by a nonlinear compression stage. At a repetition rate of 5 kHz, the drive laser provides a …

Laser wakefield acceleration (LWFA) and its particle-driven counterpart, particle or plasma
wakefield acceleration (PWFA), are commonly treated as separate, though related, branches …

Electron beam quality is paramount for X-ray pulse production in free-electron-lasers (FELs).
State-of-the-art linear accelerators (linacs) can deliver multi-GeV electron beams with …

We present experimental results on a plasma wakefield accelerator (PWFA) driven by high-
