A RELATIONSHIP FOR PLASMA SHEATHS ABOUT LANGMUIR PROBES.
Abstract
An analytical relation for the sheath about a spherical Langmuir probe was empirically derived from calculated data which reproduces this data within a mean error of better than 10 per cent. A semi-quantitative analysis verifies the functional dependence of this relation and a similar analysis develops the corresponding relationship for cylindrical geometry. In the absence of sophisticated calculations in the cylindrical case a detailed evaluation of coefficients is not possible. The relations derived, even in their present relatively crude form, should considerably aid in analysis of experimental Langmuir probe results; in particular, that involving spherical geometry.
