Coaxial cavity gyrotron with two electron beams

Abstract

A coaxial cavity gyrotron with two electron beams includes an electron gun (magnetron injection gun, “MIG,” with two beams), a coaxial cavity and a magnetic field tube. The coaxial cavity consists of two parts: an outer conductor 1 and an inner conductor 4. The two hollow electron beams 2, 3 produced by the electron gun are located between the outer conductor 1 and the inner conductor 4. The MIG with two electron beams includes inner and outer anodes 7, 8 with a cathode 9 located between the anodes. The cathode further includes two emitter rings 9a, 9b which produce the two hollow electron beams 2, 3. The entire gyrotron is immersed in the magnetic field tube such that the magnetic field profile is the same or similar to that for a coaxial gyrotron with one electron beam.
