Effects of oblique incidence and colliding pulses on laser-driven proton acceleration from relativistically transparent ultrathin targets
Julien Ferri, Evangelos Siminos, Laurent Gremillet +1
The use of ultrathin solid foils offers optimal conditions for accelerating protons from laser-matter interactions. When the target is thin enough that relativistic self-induced tr…
Collisional effects on the electrostatic shock dynamics in thin-foil targets driven by an ultraintense short pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
We numerically investigate the impact of Coulomb collisions on the ion dynamics in high-, solid density caesium hydride and copper targets, irradiated by high-intensity ($I\appr…
Fast collisional electron heating and relaxation in thin foils driven by a circularly polarized ultraintense short-pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
The creation of well-thermalized, hot and dense plasmas is attractive for warm dense matter studies. We investigate collisionally induced energy absorption of an ultraintense and u…
Enhancement of laser-driven ion acceleration in non-periodic nanostructured targets
I. Thiele, J. Ferri, E. Siminos +6
Using particle-in-cell simulations, we demonstrate an improvement of the target normal sheath acceleration (TNSA) of protons in non-periodically nanostructured targets with micron-…
Structure and evolution of magnetohydrodynamic solitary waves with Hall and finite Larmor radius effects
E. Bello-Benítez, G. Sánchez-Arriaga, T. Passot +2
Nonlinear and low-frequency solitary waves are investigated in the framework of the one-dimensional Hall-magnetohydrodynamic model with finite Larmor effects and a double adiabatic…
Electron beam driven generation of frequency-tunable isolated relativistic sub-cycle pulses
Illia Thiele, Evangelos Siminos, Tünde Fülöp
We propose a novel scheme for frequency-tunable sub-cycle electromagnetic pulse generation. To this end a pump electron beam is injected into an electromagnetic seed pulse as the l…
