<p>A microwave tube output section of a microwave tube having an output cavity (13) in which a vacuum can be maintained, has a coaxial line section (17) with an internal conductor (15) and an external conductor (16) coupled to the output cavity (13). A dielectric air-tight ring (20) forms a vacuum tight seal between the outsider internal conductor (15) and the inside of the external conductor (16). The internal conductor (15) is hollow, and is divided at a position on the output cavity side of the dielectric air-tight ring (20) in the coaxial line. A metal ring (40, 60) is attached inside each of the divided parts of the internal conductor, and these metal rings (40, 60) are welded together to form a hermetic seal between the parts of the internal conductor (15, 18). The external conductor (16) is also divided at a position on the output cavity side of the dielectric ring (20) in the coaxial line, and a metal ring (51, 33) is attached to each part of the divided external conductor, and these metal rings are welded together to form a hermetic seal between the parts of the divided external conductor (16, 19). The parts of each conductor (15, 16, 18, 19) are electrically connected together. </p> |
