Physics of Confinement

Abstract

The measured radial fluxes of particles, ion and electron heat, and toroidal angular momentum in tokamaks are usually greater than given by neoclassical transport theory. In this collisional theory, appropriate for a quiescent plasma, the random-walk step size is generally set by the width of closed banana trajectories in the steady state magnetic fields, and the step period is set by the collisional decorrelation time. At low collisionalities relevant to fusioning plasmas, detailed calculations give radial transport coefficients of the form G{sub c}{rho}{sup 2}{nu}, where G{sub c} is a dimensionless geometrical factor, {rho} is the gyroradius of the species under consideration and {nu} is the collision frequency.
