Abstract : The interaction of transverse electron beam waves with external electromagnetic fields, and the application of this interaction in microwave devices are discussed. In particular, problems involving various aspects of the so-called DCpumped electron beam amplifiers were analysed. Interaction problems in the pump field wereANALYSED BOTH THEORETICALLY AND EXPERIMENTALLY. Considerable attention was devoted to problems of noise theory, a d an expression for the minimum noi e temperature of DC-pumped amplifiers was derived. Research on the problem of designing suitable periodic structures for the input- and output-couplers of transverse field devices was performed. The theory of a harmonic generator based on cyclotron waves was presented. Three tubes were designed and tested. Two of them were cyclotron-wave amplifiers, and the third a synchronous-wave amplifier. They all worked in satisfactory agreement with theory. (Author)
