集束装置。A periodic magnetic field focusing device in which a plurality of annular permanent magnets and pole pieces are alternately arranged coaxially with the traveling wave tube around the outer periphery of a vacuum envelope containing a high frequency circuit of an input/output coaxial window-coupled traveling wave tube. In this case, the annular permanent magnet is not arranged in the input/output coaxial window, and at least two pole pieces including pole pieces adjacent to both sides of the input/output coaxial window are in phase with the vacuum envelope. A plurality of pole pieces having a larger outer diameter than the above-mentioned pole pieces are fitted together with corresponding screws, and each second pole piece on both sides of the input/output coaxial window has an outer diameter larger than that of the aforementioned pole piece. A periodic magnetic field focusing device characterized by being formed by bridging magnetic material pieces.
