Bonded Grid Development.

Abstract

This report details the results of efforts expended towards the development of a cathode and control grid assembly having the control grid solidly bonded to the cathode surface by means of a layer of insulating material. A device capable of emission and modulation was fabricated and tested. This effort demonstrated the feasibility of a control grid for microwave tubes fabricated with lithographic techniques directly on the cathode surface. When perfected this technique has two primary payoffs: (1) It will permit the use of high gain control grids at higher frequencies than possible with present shadow grid construction techniques, (2) It will also improve tube reliability, yield and construction cost. This technique will be applicable to microwave tubes used in tactical and ground based radars as well as ground based and satellite communications systems.
