Presheath and space charge sheath characteristics in front of a floating wall
Abstract
The sheath thickness and numbers of collisions from an infinite fluid model of the space between an atomic cold gas plasma and a planar wall are reported in dependence on the normalized ionization, ion elastic and charge exchange collision frequencies. The Bohm criterion validity, ion heating in double layer electric field, volume radiative recombination and related questions are discussed.
