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…
Report on the Advanced Linear Collider Study Group (ALEGRO) Workshop 2026
L. Verra, P. Muggli, B. Cross +56
The 7th ALEGRO workshop, hosted by INFN Frascati National Laboratories from 3rd to 5th March 2026, brought together the international Advanced Novel Accelerators (ANA) community to…
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…
High-energy polarized electron beams from the ionization of isolated spin polarized hydrogen atoms
Dimitris Sofikitis, Lars Reichwein, Marios G. Stamatakis +5
We propose a laser-based method for the preparation of high-energy polarized electrons, from the ionization of isolated spin-polarized hydrogen (SPH) atoms. The SPH atoms are prepa…
