Abstract

An approximate analysis of the diffusion of a steady positive column or similar discharge into a side tube, in which the plasma is supposed to terminate where the wall-sheath fills the side tube, and some allowance is made for change in electron temperature and diffusion coefficient, shows that the length of transverse plasma may often be roughly proportional to and of the order of the radius of the side tube, with a correcting factor depending on the logarithms of the radius, electron temperature and concentration at the junction of main and side tubes.
