Abstract

Electric discharge tube device provided with a thermoionic cathode that is centered by means of insulating material, characterized by the fact that measures are taken to ensure that the heat transfer from the cathode to the part of the insulator that is in contact with the cathode, exceed heat dissipation from this part to the rest of the insulator.
