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…
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…
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…
Long Living Hot and Dense Plasma from Relativistic Laser-Nanowire Array Interaction
Ehsan Eftekhari-Zadeh, Mikhail Gyrdymov, Parysatis Tavana +13
Long-living, hot and dense plasmas generated by ultra-intense laser beams are of critical importance for laser-driven nuclear physics, bright hard X-ray sources, and laboratory ast…
Plasma acceleration of polarized particle beams
Lars Reichwein, Zheng Gong, Chuan Zheng +3
Spin-polarized particle beams are of interest for applications like deep-inelastic scattering, e.g. to gain further understanding of the proton's nuclear structure. With the advent…
