A new concept for integrated cathode grid structures is presented. Two fine photo etched grids of similar geometry are brazed into a sandwich structure where they remain spaced and electrically isolated from each other by small dielectric posts. The fabrication and testing of structures based on this concept has required a study of insulating materials at elevated temperatures and grid emission suppression schemes, the results of which are discussed. Life test results are related to physico-chemical processes taking place in the direct environment of thermionic cathodes.
