Abstract

The concepts of ‘plasma edge’ and ‘collisionally modified Bohm criterion’ have occupied attention for many years since the publication of work by Bohm that gave rise to the Bohm criterion. He acknowledged that his description of the plasma-sheath transition was incomplete. We summarize work that shows that neither concept has precision, at the same time giving a critique.
