A bstract : Magnetically confined pure electron columns evolve as nearly inviscid, incompressible two‐dimensional (2‐D) fluids. Experiments on these columns have found that the decay of 2‐D turbulence leads to spontaneous formation of “vortex crystals,” which are symmetric arrays of strong vortices within a background of lower vorticity. These vortex crystals can be described as maximum fluid entropy states for a system with an ergodically mixed background and a conserved number of strong vortices.
