Abstract
Strong electric potential double layers (eφ/T e ≳10) are produced in the University of Iowa’s triple plasma device. The electron beam which results from acceleration by the double layer maintains its identity with little heating until it reaches the end of the chamber. Structure of the double layers is seen to depend upon the characteristics of the free and trapped particle species. A three‐dimensional mapping for double layers is shown. A density criterion model for the stability of double layers is also presented.Keywords
