Internal transport barriers in tokamak plasmas are explored in order to improve confinement
and stability beyond the reference scenario, used for the ITER extrapolation, and to achieve …

Tokamak discharges with improved energy confinement properties arising from internal
transport barriers (ITBs) have certain attractive features, such as a large bootstrap current …

The differences and similarities between the internal transport barriers (ITBs) of tokamak and
helical plasmas are reviewed. By comparing the characteristics of the ITBs in tokamak and …

Plasmas are created by heating gases through the absorption of ionizing radiation in the
visible through the ultraviolet part of the electromagnetic spectrum and through collisional …

This paper presents the results of three-dimensional fluid global simulations of electrostatic
ion turbulence in tokamaks with reversed magnetic shear. It is found that a transport barrier …

The effect of a sheared toroidal velocity on a transport barrier is studied. This analysis is
done by using three-dimensional global fluid simulations of electrostatic ion temperature …

The internal transport barrier (ITB) has been obtained in ELMy H-mode plasmas by neutron
beam injection and lower hybrid wave heating on the Experimental Advanced …

Results of stability analysis are presented for two types of plasma with good confinement:
internal transport barriers (ITBs) on Tore Supra and the radiative improved (RI) mode on …

It is shown here that microturbulence can be stabilized in the presence of steep temperature
and density profiles. Indeed in high plasmas, pressure profile gradients are associated with …

One of key objectives of tokamak experiments is the exploration of enhanced confinement
regimes, and the access of the internal transport barrier (ITB) formation is dealt with an …
