(under subclass 505) Subject matter in which the space-discharge device includes a cathode, and anode, and (a) an electrostatic element (e.g., a control grid) which is adapted to have an electric potential established between it and the cathode, or (b) a magnetic-field producing means; wherein the elements (a), (b) are positioned relative to the cathode and anode so as to control the space-current flow between the cathode and the anode.
