High-power millimeter wave sources are a key enabling technology in fusion energy
research. The present state of the art of application of these sources to the areas of heating …

Tokamak plasmas have a tendency to self-organization: the plasma pressure profiles
obtained in different operational regimes and even in various tokamaks may be represented …

The issue of magnetic confinement in magnetic fusion devices is addressed within a purely
magnetic approach. Using some Hamiltonian models for the magnetic field lines, the dual …

The effect of the q (r) profile on transport barrier formation has been investigated in the T-10
tokamak using rapid current ramp-up with electron cyclotron resonance heating (ECRH) …

Using Hamiltonian models for the magnetic field lines, we propose a methodology to
improve their confinement through the creation of transport barriers. A local modification of …

In this paper, recent experiments of electron cyclotron plasma heating leading to electron
internal transport barriers (ITBs) are summarized pointing out differences and common …

The aim of the paper is to study systems with one-and-a-half degrees of freedom generated
by a Hamiltonian with a quartic unperturbed part and broad perturbation spectrum. To this …

Electric field E r transverse to the current in a moving quasi-neutral plasma can (and should)
be considered using Poisson equations and densities of volume charges emerging in the …

The change in the electron temperature inside magnetic island caused by localized radio
frequency (rf) heating is studied numerically by solving the two-dimensional energy transport …

In the HL-2A tokamak a single-null divertor configuration has been established. The
separatrix of the single-null diverted plasma was identified with a filament model, and the …
