Abstract
A plurality of thermionic filaments are arranged in side-by-side relationship. A spreader electrode which may be in the form of a flat plate is placed on one side of the filaments, while an anode is placed on the other side of the filaments, with a grid being interposed between the filaments and the anode. The various aforementioned elements are given dimensions and positioned relative to each other and the voltages thereon adjusted so as to shape the trajectory of the electrons to provide a uniform distribution of electrons at the anode with a minimum dissipation of energy in the grid and spreader electrodes.
