Abstract
An approximate analysis is presented for spherical and cylindrical electrostatic probe operation under conditions such that large collision‐dominated sheaths are obtained. Analytical expressions are given for the sheath growth as a function of experimentally determined parameters. If pressure and temperatures are known, use of these results makes possible the direct interpretation of electron number density from a single probe measurement.Keywords
