Self-Adaptive Stabilization and Quality Boost for Electron Beams from All-Optical Plasma Wakefield Accelerators
D. Campbell, T. Heinemann, A. Dickson +14
Shot-to-shot fluctuations in electron beams from laser wakefield accelerators present a significant challenge for applications. Here, we show that instead of using such fluctuating…
Ultra-high-gain water-window X-ray laser driven by plasma photocathode wakefield acceleration
Lily H. A. Berman, David Campbell, Edgar Hartmann +4
X-ray free-electron lasers are large and complex machines, limited by electron beam brightness. Here we show through start-to-end simulations how to realise compact, robust and tun…
Attosecond-Angstrom free-electron-laser towards the cold beam limit
A. F. Habib, G. G. Manahan, P. Scherkl +13
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 wit…

Plasma photocathodes open a path towards tunable production of well-defined, compact electron beams with normalized emittance and brightness many orders of magnitude better than st…
All-optical density downramp injection in electron-driven plasma wakefield accelerators
D. Ullmann, P. Scherkl, A. Knetsch +16
Injection of well-defined, high-quality electron populations into plasma waves is a key challenge of plasma wakefield accelerators. Here, we report on the first experimental demons…
Demonstration of a compact plasma accelerator powered by laser-accelerated electron beams

Plasma wakefield accelerators are capable of sustaining gigavolt-per-centimeter accelerating fields, surpassing the electric breakdown threshold in state-of-the-art accelerator mod…
Plasma-photonic spatiotemporal synchronization of relativistic electron and laser beams
Paul Scherkl, Alexander Knetsch, Thomas Heinemann +23
Modern particle accelerators and their applications increasingly rely on precisely coordinated interactions of intense charged particle and laser beams. Femtosecond-scale synchroni…

We present experimental measurements of the femtosecond time-scale generation of strong magnetic-field fluctuations during the interaction of ultrashort, moderately relativistic la…
Electron bunch generation from a plasma photocathode
Aihua Deng, Oliver Karger, Thomas Heinemann +25
Plasma waves generated in the wake of intense, relativistic laser or particle beams can accelerate electron bunches to giga-electronvolt (GeV) energies in centimetre-scale distance…
