To solve the problem of a conventional gyrotron tube, in which when the conventional gyrotron tube is horizontally placed by being fixed at only one place in a mounting flange, concentricity between the gyrotron tube and a magnetic field generator may be insufficient.
A gyrotron device includes: a gyrotron tube 1 in which an electron gun 11 generating an electron beam is provided at one end and an output window 12 outputting a microwave is provided at the other end; a magnetic field generator 2 formed cylindrically by concentrically surrounding the gyrotron tube, for generating a magnetic field necessary for operation of the gyrotron tube; a flange 3 for fixing the gyrotron tube on one side face of the magnetic field generator; and a spacer 4 mounted on an outer periphery of the gyrotron tube near the electron, inserted into a cylindrical portion of the gun magnetic field generator from a side face on which the flange is fixed to be provided between the gyrotron tube and the magnetic field generator. The spacer is used to ensure concentricity between the gyrotron tube and the magnetic field generator.
