Abstract : A stable high-pressure electric discharge is produced using an electron beam to ionize the gas. The attachment instability in the discharge, discovered under this program, has been investigated in the gas mixtures (He:CO2:H2O) = (74:0:2), (9:1:0), (1:1:0) (mole fraction) and a theory predicting the instability has been derived. Experimental measurements of the discharge parameters for instability onset agree well with theoretical predictions. It appears that the onset of discharge arcing may be associated with this phenomenon, and theoretical understanding of it is expected to be of considerable importance in electric discharge gas laser systems.
