An Empirical Approach to Tokamak Transport

ABSTRACT This lecture will present an overview of the important considerations related to particle and energy transport in a tokamak. Transport in tokamaks can be inferred by analyzing the experimental data in terms of the one dimensional magnetic field diffusion equation and the particle and energy conservation equations. This approach will be illustrated by considering current penetration during the startup phase, density buildup in high density discharges, as well as the ion and electron energy balance in PLT ohmically heated discharges. Areas requiring further research will be discussed.
