Abstract: A method of manufacturing an indirectly heated cathode wherein a cup-shaped member having an end face provided with an aperture therein is secured to a disclike cathode support along an inner edge to form a wedge-shaped gap which is thereafter filled with a metal powder. The metal powder is then sintered to provide a thermally conductive body between the heater housing and the cathode disc from which metal particles do not work loose.
