ABSTRACT:
A gyrotron having a mode converter located in the path of a wave passing passage, the mode converter comprising a means for mode-converting electromagnetic wave into a radiating electromagnetic wave having an annular-shaped power distribution in a plane perpendicular to the direction in which the electromagnetic wave propagates, a ring-shaped mirror (annular mirror) for reflecting the radiating electromagnetic wave which has been converted by the mode converting means, and a waveguide tube having a kerf (i.e., a cutting portion of the tube) opposed to the annular mirror to receive the electromagnetic wave reflected by the annular mirror.
