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…
Galilean Electromagnetic Particle-in-Cell Code
Alexander Pukhov, Nina Elkina, Tom Wilson
We introduce a Galilean electromagnetic particle-in-cell (GEM-PIC) algorithm, which transforms the full set of Maxwell equations and the Vlasov equation into the boosted coordinate…
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…
Kination and the Inert Doublet Model
Geneviève Bélanger, Nicolás Bernal, Andreas Goudelis +1
The inert doublet model is a two-Higgs-doublet extension of the standard model that provides a minimal and versatile framework for frozen-out dark matter. Assuming standard cosmolo…
Efficient Simulation of Electron-Positron Pair Production in Foam Targets in the low Ï-Regime
Oliver Mathiak, Lars Reichwein, Alexander Pukhov
The generation of electron-positron pairs using direct laser-accelerated electrons and a cone-shaped reflector target for the generation of strong electromagnetic fields is investi…
