摘要：
At least one permanent magnet and a pole piece having a projection is contained in an evacuated envelope formed by an anode cylinder and yokes on the opposite ends thereof. The permanent magnet and the pole piece is clamped between one yoke and a holder secured to the inner wall of the anode cylinder. The holder is provided with an opening a little smaller than the outer diameter of the projection and the projection is force-fitted into the opening to project into an interaction space defined between anode vanes and the cathode electrode.
