とする進行波管。 In order to focus the electron beam passing through the slow wave circuit, pole pieces (circular magnetic pole pieces) and permanent magnets are arranged alternately in the slow wave circuit, and in order to cool the delay circuit, the outer peripheries of the pole pieces and permanent magnets are arranged alternately. In the traveling wave tube, the outer diameter of the permanent magnet is smaller than the outer diameter of the pole piece, and the inner circumferential surface of the cooling fin attached to the outer periphery of the pole piece and the outer circumference of the permanent magnet are smaller than the outer diameter of the pole piece. A shim (iron piece) for fine adjustment of the center magnetic field of the slow wave circuit is placed between the outer peripheral surface.
A traveling wave tube characterized by having a space in which a.
