Study of turbulent transport in magnetized plasmas with flow using symplectic maps
Autor: Jorge Torres, Julio J. Martinell
Publikováno v: Chaos: An Interdisciplinary Journal of Nonlinear Science. 33
Turbulent transport in a magnetized plasma of the kind found in tokamaks is modeled by a 2D wave spectrum that allows reduction to a symplectic map. The properties of particle transport when chaos sets in are analyzed in various circumstances includi

Turbulent transport in magnetically confined plasmas with flow in the drift approximation
Autor: Julio J. Martinell, J. Torres, C. A. Tafoya
Publikováno v: Radiation Effects and Defects in Solids. 175:994-997
Turbulence-driven transport in magnetically confined plasmas is the dominant process of energy loss and is generally ascribed to the action of some type of drift waves. The detailed process of self...

MHD equilibria with magnetic islands in the TJ-II heliac
Autor: L. Benjamín Centurión, Julio J. Martinell
Publikováno v: Radiation Effects and Defects in Solids. 174:9-18
Magnetic islands normally form at the low-order magnetic rational surfaces in toroidal confinement systems when a symmetry-breaking perturbation arises. In stellarators, the equilibrium sta...

On the bootstrap current in the TJ-II stellarator
Autor: Julio J. Martinell, Katia Camacho
Publikováno v: Radiation Effects and Defects in Solids. 172:108-118
Bootstrap current in stellarators is usually very small since they operate solely with the magnetic confinement provided by the external currents. Since plasma pressure gradients are always present, the bootstrap current is always finite, but the mag

An Optimal Burn Regime in a Controlled Tokamak Fusion Power Plant
Autor: Javier E. Vitela, Julio J. Martinell
Publikováno v: IEEE Transactions on Plasma Science. 44:296-305
The optimal conditions for the burn regimes of a tokamak fusion power plant are obtained under the assumption that electron and ion temperatures can be controlled independently by means of external auxiliary heating. The study of the system is based

Effect of suprathermal electrons flux on the ambipolar electric field in stellarators
Autor: Julio J. Martinell
Publikováno v: Radiation Effects and Defects in Solids. 171:103-108
Low collisionality plasmas in non-axisymmetric toroidal magnetic devices have significant radial particle fluxes due to trapped particles in the magnetic ripples. The associated ambipolar radial electric field cannot be quantitatively reproduced by s
