<p>An output power adjusting mechanisms (44) for adjusting output power is provided on a wave guide (38) of a high frequency output section (19) coupled to an output cavity (24). The output power adjusting mechanisms (44) is located at a position apart away from the output cavity (24) by a distance of 1/8 wavelength or [(1/8 wavelength) × odd number]. The output power adjusting mechanism (44) includes a reflection adjusting part (46) which is provided in the tube wall of the output tube (38) so as to be displaceable in the inward and outward directions of the output tube (38). The output power is adjusted by displacing the reflection adjusting part (46).</p> |
