Investigations of I-V characteristics and electron beam generation efficiency in a high-voltage abnormal glow discharge in the direct current mode in helium at a pressure range of 2.17-10.2 Torr under conditions of minimizing controlled and uncontrolled impurities in the working medium have been carried out. The non-monotonically increasing character of the I-V characteristics is demonstrated and electron beam generation efficiencies of ~ 80% are obtained. Keywords: gas discharge, helium, electron beam, efficiency.
