Popis: A self‐consistent quasistatic equilibrium for a non‐neutral cylindrical electron vortex has been found using the two‐dimensional relativistic electron fluid equations. While other work on electron vortices considered a regime where the vortex radius is much smaller than the collisionless skin depth λ=c/ωp, this equilibrium is valid for large‐radius, diamagnetic vortices and predicts a maximum radius of 23/2λ for a highly relativistic electron vortex. The vortex model shows good agreement with observations of diamagnetic electron vortices in two‐dimensional electromagnetic particle‐in‐cell simulations of magnetically insulated transmission lines.
