TLDR
In this paper, the authors investigated the class of such distributions for a finite length cylindrical column and showed that the density is essentially constant out to some surface of revolution and then falls off abruptly.Abstract:
The electrons of a pure electron plasma may be in thermal equilibrium with each other and still be confined by static magnetic and electric fields. Since the electrons make a significant contribution to the electric field, only certain density profiles are consistent with Poisson’s equation. The class of such distributions for a finite length cylindrical column is investigated. In the limit where the Debye length is small compared with the dimensions of the column, the density is essentially constant out to some surface of revolution and then falls off abruptly. The falloff in density is a universal function when measured along the local normal to the surface of revolution and scaled in terms of the Debye length. The solution for the shape of the surface of revolution is simplified by passage to the limit of zero Debye length.read more

Transport to thermal equilibrium of a pure electron plasma
Thomas M. O'Neil,C. F. Driscoll +1 more
TL;DR: In this article, the authors considered the transport of a pure electron column across an axial magnetic field, the transport being due to binary electron-electron collisions and the Boltzmann equation was expanded in inverse powers of the magnetic field with the radial electric field and density gradient ordered selfconsistently.

Vlasov Equilibria and Stability of an Electron Gas
TL;DR: In this paper, self-consistent Vlasov equilibria with space charge were constructed for a pure electron gas radially confined in a uniform external magnetic field, and a sufficient condition was obtained for the stability of these non-uniform equilibrium to electrostatic perturbations.
