Controlling the boundary layer in fusion-grade, high-performance, plasma discharges is
essential for the successful development of toroidal magnetic confinement power generating …

The magnetic confinement concept of thermonuclear plasma is one of the areas of
controlled fusion research develo** in the past 50 years in a quest for clean and unlimited …

Fractal structures appear in many situations related to the dynamics of conservative as well
as dissipative dynamical systems, being a manifestation of chaotic behaviour. In open area …

The magnetic field line structure in a tokamak can be obtained by direct numerical
integration of the field line equations. However, this is a lengthy procedure and the analysis …

Shearless transport barriers appear in confined plasmas due to non-monotonic radial
profiles and cause localized reduction of transport even after they have been broken. In this …

The creation of an outer layer of chaotic magnetic field lines in a tokamak is useful to control
plasma-wall interactions. Chaotic field lines (in the Lagrangian sense) in this region …

The main component of the Dynamic Ergodic Divertor (DED) consists of a set of coils
installed in the TEXTOR tokamak which creates resonant magnetic perturbations …

The magnetic field line structure of tokamaks with reversed magnetic shear is analyzed by
means of a nontwist map model that takes into account non-integrable perturbations that …

The ergodic magnetic limiter is a device designed to generate a cold boundary layer of
chaotic magnetic field lines at the peripheral region of a tokamak, with the main purpose of …

Reversed magnetic shear configurations in tokamaks reduce substantially particle diffusivity
and improve plasma confinement due to the formation of a transport barrier, as a result of …
