It is shown that vortex structures exist in high-density non-axisymmetric crossed-field equilibrium flow in a crossed-field device. With the aid of perturbation theory and the guiding-center approximation and assuming a constant electron particle number density in the electron layer, we determine equipotential surfaces, electron trajectories, and the corrugated boundary of the electron layer. As the electron density approaches the (critical) Brillouin density, a vortex structure with regions of negative potential forms near the cathode surface.
