Abstract: A METHOD OF MANUFACTURING AN ELECTRIC DISCHARGE TUBE BY FIRST COATING NON-EMITTING ELECTRODES SUCH AS AN ANODE WITH A LAYER OF NICKEL AND THEN A LAYER OF GOLD, AND THEN HEATING THE ELECTRODE DURING PUMPING TO A DEGASSING TEMPERATURE ABOUT 780*C. THE EMMISSION-SUPPRESSING CHARACTERISTICS OF THE NON-EMITTING ELECTRODES ARE MAINTAINED EVEN THOUGH THE GOLD DISSOLVES IN THE NICKEL.
