波管。 In a traveling wave tube in which a magnet and a pole piece are attached to the outer periphery of a vacuum envelope that surrounds the vacuum region of a slow wave circuit, the pole piece has a double structure, and one wedge-shaped part that also has a tapered surface is attached to the tapered surface. The pole piece is inserted into the other part, which has a tapered surface with the same inclination as the pole piece, to maintain close contact between the pole piece and the vacuum envelope, and the vacuum envelope is tightened so that the inner surface of the vacuum envelope A traveling wave tube characterized by a structure in which loosening between the inner surface and the slow wave circuit portion in contact with the inner surface is suppressed.
