Recent Results From the DIII–D Tokamak*
The goal of the DIII–D program is to provide the integrated basis for commercially attractive steady state fusion power plants. Significant progress toward this goal has been achieved, enabled by system improvements including an error field correction coil, an expanded diagnostic set, a digital plasma control system, and high power rf systems. Simultaneous improvements in both the confinement a...

متن کاملAlpha-channeling simulation experiment in the DIII-D tokamak.
Alfvén instabilities can reduce the central magnetic shear via redistribution of energetic ions. They can sustain a steady state internal transport barrier as demonstrated in this DIII-D tokamak experiment. Improvement in burning plasma performance based on this mechanism is discussed.
متن کاملMultivariable Shape Control Development on the Diii–d Tokamak
In this paper, we describe recent work on plasma shape and position control at DIII–D. This control consists of two equally challenging problems — the problem of identifying what the plasma actually looks like in real time, i.e. measuring the parameters to be controlled, and the task of determining the feedback algorithm which best controls these plasma parameters in a multiple input-output sys...
متن کاملDivertor Plasma Physics Experiments on the Diii–d Tokamak
DIVERTOR PLASMA PHYSICS EXPERIMENTS ON THE DIII–D TOKAMAK. In this paper we present an overview of the results and conclusions of our most recent divertor physics and development work. Using an array of new divertor diagnostics we have measured the plasma parameters over the entire divertor volume and gained new insights into several divertor physics issues. We present direct experimental evide...
