Solution to a collisionless shallow-angle magnetic presheath with kinetic ions

Abstract:

Using a kinetic model for the ions and adiabatic electrons, we solve a steady state, electron-repelling magnetic presheath in which a uniform magnetic field makes a small angle $\alpha \ll 1$ (in radians) with the wall. The presheath characteristic thickness is the typical ion gyroradius ${\rho }_{{\rm{i}}}$. The Debye length ${\lambda }_{{\rm{D}}}$ and the collisional mean free path of an ion λ mfp satisfy the ordering λ D Lt ρ i Lt α λ mfp, so a quasineutral and collisionless model is used....
