Proposal of a high efficiency tube for high power millimetre or submillimetre wave generation The gyro-peniotron

Abstract

This paper proposes a new cyclotron fast-wave tube named the ‘gyro-peniotron’, which is promising as a highly efficient and powerful source of millimetre or sub-millimetre waves, and reports the analytical results of its operational characteristics using some computer simulations. The analytical results assuming two operating conditions of ω0;≃ ωc and ω0≃3ωc for the 35 GHz gyro-peniotron in the TE021 cavity mode predict a high efficiency of 63% and a quite high output power of 48 MW at a beam voltage of 80 kV and a magnetic field of 13 kG in the case of ω0≃ωc, and also, an efficiency of 48% and a power of 9 MW at a beam voltage of 60 kV and a magnetic field of 4·425 kG in the ease of ω0≃3ωc
