The presheath characteristic thickness is the typical ion gyroradius $\\rho_{\\text{i}}$. The Debye length $\\lambda_{\\text{D}}$ and the collisional mean free path of an ion $\\lambda_{\\text{mfp}}$ satisfy the ordering $\\lambda_{\\text{D}} \\ll \\rho_{\\text{i}} \\ll \\alpha \\lambda_{\\text{mfp}}$, so a quasineutral and collisionless model is used.
