A plasma photocathode for spin-polarized electron beams via state-selected hydrogen halide photofragments
Lars Reichwein, Thomas C. Wilson, Dimitris Sofikitis +6
Spin-polarized electron beams are essential tools for probing fundamental symmetries and for the search beyond the Standard Model. While plasma-based accelerators are a promising p…

Pinching injection in wakefields for spin-polarized electron beams
Lars Reichwein, Dimitris Sofikitis, Oliver Mathiak +5
Pinching of the driver beam in plasma wakefield acceleration is generally considered an unwanted effect that needs to be mitigated. Here, we propose that this effect can be utilize…

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…
