The Numerical Solution of the Kinetic Sheath Using an Eulerian Vlasov Code

The solution of the collisionless kinetic sheath at a plasma-wall transition is studied numerically using an Eulerian Vlasov code, for the one-dimensional (1D) phase-space problem. Because of its very low noise level, the Eulerian Vlasov code allows an accurate study of the non-neutral collisionless kinetic sheath, especially in the low density regions of the phase-space. Some of the basic macroscopic quantities associated with the sheath equilibrium are calculated.
