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…
An electron injector for the Electron-Ion Collider based on proton-driven plasma wakefield acceleration
J. P. Farmer, H. Jaworska, A. Caldwell +5
We describe an electron bunch injector scheme based on proton-driven plasma wakefield acceleration for the Electron-Ion Collider. The proton bunches needed to drive the plasma wake…
Radiative depolarization of high-energy electron beams in wakefield accelerators
Oliver Mathiak, Lars Reichwein, Alexander Pukhov +2
The preservation of witness beam polarization in wakefield accelerators will be crucial for future collider applications. While extensive theoretical studies on the injection and i…
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…
Electron-positron pair generation using a single kJ-class laser pulse in a foam-reflector setup
Oliver Mathiak, Lars Reichwein, Alexander Pukhov
We investigate the process of creating electron-positron pairs from laser-matter interaction in pre-ionised foam targets using particle-in-cell simulations. A high-intensity laser…
