Toward Terahertz Magnetrons: 210-GHz Spatial-Harmonic Magnetron With Cold Cathode

摘要

The development of a 210-GHz spatial-harmonic magnetron with a cold secondary-emission cathode is presented. The development includes a detailed self-consistent tube simulation and optimization. Based on these results, 210-GHz tubes providing over 1-kW peak power were produced and tested. Experimental results are consistent with the simulation.
