TUNNEL CATHODES FOR MICROWAVE TUBES
Abstract
Experiments with anodized niobium are described. The results obtained with different metal counter-electrodes are discussed. The barrier shape is computed and evaluated. Vacuum emission experiments with anodized niobium are described. The usefulness of cadmium sulfide for the insulator film is discussed. Experiments with painted and sprayed films are described. Vacuum emission tests with gold--cadmium sulfide--gold cathodes are discussed. The theoretical analysis of hot electrons in metals is briefly discussed. Plans for future work are described. (Author)
