Energy-optimized scaling laws for self-guided laser wakefield accelerators
Petr Valenta, Marcel Lamač, Kyle G. Miller +4
Laser wakefield acceleration promises compact electron accelerators for applications in medicine, industry, and fundamental science. Yet, despite rapid progress, accurately predict…
Optimized matching conditions for self-guided laser wakefield accelerators
P. Valenta, K. G. Miller, B. K. Russell +4
We revisit the matching conditions for self-guided laser pulse propagation in plasma and refine their formulation to maximize the energy of electrons produced via laser wakefield a…
Photon Accelerator in Magnetized Electron-Ion Plasma
Sergei Bulanov, Stepan Bulanov, Timur Esirkepov +6
Strong magnetic fields and plasmas are intrinsically linked in both terrestrial laboratory experiments and in space phenomena. One of the most profound consequences of that is the…
Injection and Acceleration of Electrons by Radially Polarized Laser Pulses in a Plasma Channel
P. Hadjisolomou, P. Valenta, R. Shaisultanov +4
We consider injection and subsequent acceleration of electrons in narrow plasma channels irradiated by linearly and radially polarized ultraintense laser pulses. Using three-dimens…
Towards controlling electron charge with nanoparticle assisted laser wakefield accelerators
AlžbÄta Å pádová, Petr Valenta, Sebastian Lorenz +4
This study explores nanoparticle-assisted electron injection as a method for controlling beam charge in laser wakefield acceleration through particle-in-cell simulations. We system…
Bayesian optimization of electron energy from laser wakefield accelerators
P. Valenta, T. Zh. Esirkepov, J. D. Ludwig +2
We use Bayesian optimization in combination with three-dimensional particle-in-cell simulations to determine the optimal laser and plasma parameters that, for a given laser pulse e…
