Bifurcation effects on the plasma edge of tokamaks with ergodic limiter.
(European Physical SocietyEspoo, 2013-07-01)
In the present paper, we solve a twist symplectic map for the action of an ergodic magnetic limiter in a large aspect-ratio tokamak. In this model, we study the bifurcation scenarios that occur in the remnants regular ...
Recurrence quantification analysis of turbulent fluctuations in the plasma edge of Tokamak Chauffage Alfveacuten Breacutesilien tokamak
(AMER INST PHYSICS, 2010)
Recurrences are close returns of a given state in a time series, and can be used to identify different dynamical regimes and other related phenomena, being particularly suited for analyzing experimental data. In this work, ...
Kinetic ion effect on geodesic acoustic Alfven modes in tokamaks
(AMER INST PHYSICS, 2009)
Using a quasitoroidal set of coordinates with coaxial circular magnetic surfaces, the Vlasov equation is solved for collisionless plasmas, and the dielectric tensor is found for large aspect ratio tokamaks in a low frequency ...
Development of Magnetohydrodynamic Modes During Sawteeth in Tokamak Plasmas
(American Institute Of Physics, 2013-07)
A dynamical analysis applied to a reduced resistive magnetohydrodynamics model is shown to explain the chronology of the nonlinear destabilization of modes observed in tokamak sawteeth. A special emphasis is put on the ...

Analytical solutions for Tokamak equilibria with reversed toroidal current
(AMER INST PHYSICS, 2011)
In tokamaks, an advanced plasma confinement regime has been investigated with a central hollow electric current with negative density which gives rise to non-nested magnetic surfaces. We present analytical solutions for ...
Tokamak TCABR: Acquisition system, data analysis, and remote participation using MDSplus
(ELSEVIER SCIENCE SALAUSANNE, 2012)
Each plasma physics laboratory has a proprietary scheme to control and data acquisition system. Usually, it is different from one laboratory to another. It means that each laboratory has its own way to control the experiment ...
