Effects of the Internal Transport Barrier in the plasma confinement with Resonant Magnetic Perturbations
P. Haerter, L. C. Souza, R. L. Viana +1
In the pursuit of steady-state fusion energy, Advanced Tokamak regimes rely on Internal Transport Barriers (ITBs) with reversed magnetic shear. While Resonant Magnetic Perturbation…
Larmor radius effect on the control of chaotic transport in tokamaks
L. A. Osorio-Quiroga, M. Roberto, R. L. Viana +2
We investigate the influence of the finite Larmor radius on the dynamics of guiding-center test particles subjected to an drift in a large aspect-rat…
ExB drift particle transport in tokamaks
L. A. Osorio-Quiroga, G. C. Grime, M. Roberto +3
In tokamaks, modification of the plasma profiles can reduce plasma transport, improving particle confinement. However, this improvement is still not completely understood. In this…
Shearless bifurcations in particle transport for reversed shear tokamaks
G. C. Grime, M. Roberto, R. L. Viana +2
Some internal transport barriers in tokamaks have been related to the vicinity of extrema of the plasma equilibrium profiles. This effect is numerically investigated by considering…
Area-preserving maps models of gyro-averaged chaotic transport
J. D. da Fonseca, D. del-Castillo-Negrete, I. L. Caldas
Discrete maps have been extensively used to model 2-dimensional chaotic transport in plasmas and fluids. Here we focus on area-preserving maps describing finite Larmor radius (FLR)…
