Magnetically confined charged particles: From steep density profiles to the breaking of the adiabatic invariant
Aurélien Cordonnier, Yohann Lebouazda, Xavier Leoncini +1
This study examines the stability of Vlasov equilibrium solutions for magnetically confined plasmas, derived through the principle of maximum entropy. By treating the toroidal limi…
Full Self-Consistent Vlasov-Maxwell Solution
Aurélien Cordonnier, Xavier Leoncini, Guilhem Dif-Pradalier +1
Full self-consistent stationary Vlasov-Maxwell solutions of magnetically confined plasmas are built for systems with cylindrical symmetries. The stationary solutions are thermodyna…
Sticky islands in stochastic webs and anomalous chaotic cross-field particle transport by ExB electron drift instability
D. Mandal, Y. Elskens, X. Leoncini +2
The ExB electron drift instability, present in many plasma devices, is an important agent in cross-field particle transport. In presence of a resulting low frequency electrostatic…
Influence of toroidal flow on stationary density of collisionless plasmas
Elias Laribi, Shun Ogawa, Guilhem Dif-Pradalier +3
Starting from the given passive particle equilibrium particle cylindrical profiles, we built self-consistent stationary conditions of the Maxwell-Vlasov equation at thermodynamic e…
Tailoring steep density profile with unstable points
Shun Ogawa, Xavier Leoncini, Alexei Vasiliev +1
The mesoscopic properties of a plasma in a cylindrical magnetic field are investigated from the view point of test-particle dynamics. When the system has enough time and spatial sy…
Dynamics of vortices and drift waves: a point vortex model
Xavier Leoncini, Alberto Verga
The complex interactions of localized vortices with waves is investigated using a model of point vortices in the presence of a transverse or longitudinal wave. This simple model sh…
Stabilizing the intensity for a Hamiltonian model of the FEL
R. Bachelard, C. Chandre, D. Fanelli +2
The intensity of an electromagnetic wave interacting self-consistently with a beam of charged particles, as in a Free Electron Laser, displays large oscillations due to an aggregat…
Nonlinear Evolution of q=1 Triple Tearing Modes in a Tokamak Plasma
Andreas Bierwage, Satoshi Hamaguchi, Masahiro Wakatani +2
In magnetic configurations with two or three q=1 (with q being the safety factor) resonant surfaces in a tokamak plasma, resistive magnetohydrodynamic modes with poloidal mode numb…
