Abstract

A model to describe an unmagnetized (ρ_i/a∼1; ρ_i is the thermal ion gyro-radius and a is the plasma minor radius) plasma in a three-dimensional, inhomogeneous magnetic topology is presented. Ion trajectories are integrated numerically and all finite-Larmor radius effects are retained exactly. Numerical simulations relevant to the low and high confinement modes of the toroidal heliac H1-National Facility [Hamberger et al., Fusion Technol. 17, 123 (1990)] are presented and discussed.
