    摘要： The present invention includes a circular waveguide with a cylindrical shape, a lead-in side rectangular waveguide, and a lead-out side rectangular waveguide. The circular waveguide includes a dielectric airtight window that partitions an internal space into a lead-in side and a lead-out side and one welding collar disposed on the circumference of an end face of at least one of the lead-in side and the lead-out side. The lead-in side rectangular waveguide and the lead-out side rectangular waveguide are connected to circular connecting plates that are connected to the corresponding end faces of the circular waveguide; and another welding collar to be welded to the one welding collar is provided on the circumference of at least one of the connecting plates. A groove or a hole, into which a rotation restriction jig for restricting rotation in the circumferential direction is fit, is formed in each of the one welding collar and the other welding collar; and the entire circumference of each of the one welding collar and the other welding collar including the groove or the hole is fixed by welding.

    摘要： This klystron (10) comprises an electron gun unit (A), a plurality of resonance cavities (14a) to (14j), a collector (15), and a plurality of drift tubes (16a) to (16k). The plurality of resonance cavities (14a) to (14j) include an input cavity (19), a plurality of intermediate cavities (21b) to (21i), and an output cavity (20), positioned sequentially along the direction in which electrons (11) travel from the electron gun unit (A). The plurality of intermediate cavities (21b) to (21i) include a plurality of second harmonics cavities (23d), (23g). The collector (15) traps the electrons (11) that have passed through the plurality of resonance cavities (14a) to (14j). The plurality of drift tubes (16a) to (16k) are provided between the electron gun unit (A) and the input cavity (19), between each of the plurality of resonance cavities (14a) to (14j), and between the output cavity (20) and the collector (15).
