Transport Effects Induced by Resistive Ballooning Modes and Comparison with High-βpISX-BTokamak Confinement

The transport effects induced by resistive ballooning modes are estimated from a theory, and are found to be mainly thermal electron conduction losses. An expression for electron thermal diffusivity ${\ensuremath{\chi}}_{e}$ is derived. The theoretical predictions agree well with experimental values of ${\ensuremath{\chi}}_{e}$ obtained from power balance for the ISX-$B$ plasmas at high poloidal beta.
