Generating multi-GeV electron bunches using single stage laser wakefield acceleration in a 3D nonlinear regime
W. Lu, M. Tzoufras, C. Joshi +5
The extraordinary ability of space-charge waves in plasmas to accelerate charged particles at gradients that are orders of magnitude greater than in current accelerators has been w…
Fluctuations and control in the Vlasov-Poisson equation
Ricardo Lima, R. Vilela Mendes
In this paper we study the fluctuation spectrum of a linearized Vlasov-Poisson equation in the presence of a small external electric field. Conditions for the control of the linear…
A stochastic representation for the Poisson-Vlasov equation
R. Vilela Mendes, Fernanda Cipriano
A stochastic representation for the solutions of the Poisson-Vlasov equation is obtained. The representation involves both an exponential and a branching process. The stochastic re…
dHybrid: a massively parallel code for hybrid simulations of space plasmas
L. Gargaté, R. Bingham, R. A. Fonseca +1
A massively parallel simulation code, called \textit{dHybrid}, has been developed to perform global scale studies of space plasma interactions. This code is based on an explicit hy…
Kinetics of the collisionless expansion of spherical nanoplasmas
F. Peano, F. Peinetti, R. Mulas +2
The collisionless expansion of spherical plasmas composed of cold ions and hot electrons is analyzed using a novel kinetic model, with special emphasis on the influence of the elec…
Controlled Shock Shells and Intracluster Fusion Reactions in the Explosion of Large Clusters
F. Peano, R. A. Fonseca, J. L. Martins +1
The ion phase-space dynamics in the Coulomb explosion of very large ( atoms) deuterium clusters can be tailored using two consecutive laser pulses with different…
