Two-dimensional guiding-center transport of a pure electron plasma

Cross-field particle transport is discussed for the case of a magnetically confined pure electron plasma column. The analysis is based on a 2D guiding-center model and yields a flux which scales with magnetic field strength like 1/B. The magnitude of the flux exceeds that predicted previously provided that two conditions are met. The axial bounce frequency for a typical electron must exceed the E×{}B drift rotation frequency, and this rotation frequency must be a nonmonotonic function of radius.
