Recent advances in the development of such low-voltage magnetrons, 210 GHz tubes, and magnetrons with an extended lifetime are reviewed. Potentials for further improving the performance of spatial-harmonic magnetrons are considered as well.encold cathodemagnetronmillimeter-wavelength oscillatorsecondary-emission cathodevacuum tubeTechnikConference Paper10.1109/MSMW.2016.7538218Other
