GYROTRON.

摘要

A gyrotron device comprising a magnetron injection gun for emitting a sectionally-ring-shaped electron beam, a superconducting coil for applying magnetic field to the electron beam emitted from the gun, a ring-shaped resonator mirror for quasi-optically reflecting and resonating those electromagnetic waves which are oscillated when the electron beam passes along the magnetic lines of force generated by the superconducting coil and which propagate in the radial direction, while radially emitting a portion of the electromagnetic waves, and a plurality of transmission mirrors for quasi-optically reflecting and transmitting the electromagnetic waves which have been emitted in the radial direction of the resonator mirror.
