Electron bunches produced in self-modulated laser wakefield experiments usually have a broad energy distribution, with most electrons at low energy (1–3 MeV) and only a small fraction at high energy. We propose and investigate further acceleration

Point-Vortex Approach in Two-Dimensional Turbulence

Autor: B. N. Kuvshinov, T. J. Schep

Publikováno v: Физика плазмы. 42:535-548

The properties of two-dimensional turbulence in a circular domain are investigated within the framework of the punctuated point-vortex model. Vortex dynamics is governed by Hamiltonian equations, and it is interrupted by instantaneous events resultin

The transitional phase from local to global chaos in the magnetic field of a reconnecting current layer is investigated. Regions where the magnetic field is stochastic exist next to regions where the field is more regular. In regions between stochast

Dynamics of plasma vortices: The role of the electron skin depth

Autor: J Bergmans, J.H. Mentink, T. J. Schep, Leon Lpj Kamp

Publikováno v: Physics of Plasmas, 12(5), 052311-1/14. American Institute of Physics

The drift-Alfvén equations for a quasineutral plasma that is permeated by a strong background magnetic field describe the plasma dynamics in the transverse plane. Three scalar fields—which are linear combinations of parallel current, fluid vortici

Europhysics Letters, 66, 492-498

The effect of Raman backscattering (RBS) on high-energy electron generation in laser-plasma interaction has been investigated for laser intensities well above the wave breaking and electron trapping threshold. One-dimensional particle-in-cell simulat
