Here, the design, construction and experimental investigation of a 20 kW, 28 GHz gyrotron (2nd harmonic) are reported. This tube was designed to evaluate new emitters for future highly efficient and reliable fusion gyrotrons and for material processing applications. Following experimental results have been achieved in CW operation: 22.5 kW output power at 23.4 kV electron beam voltage and 2.23 A beam current with the world record efficiency of 43 %.Microwave-Materials-ProcessingWirkungsgradEfficiencyKernfusionEmitter-TechnologienNuclear-FusionEmitter-TechnologiesGyrotronMikrowellenmaterialprozesstechnikGyrotronMalygin Antonauth1322411BOOK9910346767503321Design and Experimental Investigation of a Second Harmonic 20 kW Class 28 GHz Gyrotron for Evaluation of New Emitter Technologies3034970UNINA
