Abstract:

A simple theoretical model with different electron and heavy particle temperatures is applied to a high pressure helium arc in a cooled cylindrical duct. Single temperature theories predict a universal curve independent of duct radius for dissipated power versus the product of the axial electric field and the duct radius. The experimentally measured deviations from this universal curve are explained by the two temperature theory. The current-voltage characteristic of a cylindrical wall segment probe is also understood in terms of an elevated electron temperature, often exceeding the heavy particle temperature by an order of magnitude near the wall.
