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 …

Tokamaks have demonstrated excellent plasma confinement capability because of their
symmetry but has an intrinsic drawback because of their pulsed inductive operation. Efforts …

This is a textbook on theoretical plasma physics, which is the science of extremely hot gases
which make up most of the universe and which are used extensively in fusion energy …

A multi-species fluid model is described for the steady state parallel and radial force balance
equations in axisymmetric tokamak plasmas. The bootstrap current, electrical resistivity, and …

The physics model of electron cyclotron heating (ECH) and current drive (ECCD) is
becoming well validated through systematic comparisons of theory and experiment. This …

Significant progress has been made in the area of advanced modes of operation that are
candidates for achieving steady state conditions in a fusion reactor. The corresponding …

Peaked pressure profiles and central ion temperatures up to 20 keV are observed in DIII-D H-
mode discharges with a central region of strongly reversed magnetic shear. Short …

Physics elements and advances crucial for the development of axisymmetric
magnetohydrodynamic equilibrium reconstruction to support plasma operation and data …

Localized currents due to electron cyclotron current drive have been measured for the first
time in experiments on the DIII-D tokamak. The location of driven current in the plasma has …

The STEP (Stability, Transport, Equilibrium, and Pedestal) integrated-modeling tool has
been developed in OMFIT to predict stable, tokamak equilibria self-consistently with core …
