  • Magnetrons
    Patent number: 7026761
    Abstract: A magnetron includes a decoupling plate located between the end hat of the magnetron cathode and an output coupling member. The use of the decoupling plate presents a high impedance and gives a resonant circuit which is arranged to be resonant at the operating frequency of the magnetron. This prevents or reduces power loss due to capacitive coupling. In another arrangement, the decoupling plate is mounted to a post on the end hat of the magnetron cathode.
    Type: Grant
    Filed: March 30, 2001
    Date of Patent: April 11, 2006
    Assignee: E2V Technologies (UK) Limited
    Inventors: Kesar Saleem, Michael B Brady
  • Magnetron anodes
    Patent number: 6841940
    Abstract: In a magnetron anode, an anode surrounds a central cathode. The anode is of a segmented structure having a plurality of annular segments stacked together along its length. Each annular segment includes a strap, the strap being distributed substantially along the entire axial length of the anode vanes. This enables mode separation to be achieved, even for long anode lengths and, hence, permits high power operation to be achieved. In addition, the segmented structure of the anode gives a mechanically robust design.

  • Magnetrons
    Publication number: 20030150722
    Abstract: A magnetron includes a decoupling plate (16) located between the end hat (15) of the magnetron cathode (21) and an output coupling member (11). The use of the decoupling plate (16) presents a high impedance and gives a resonant circuit which is arranged to be resonant at the operating frequency of the magnetron. This prevents or reduces power loss due to capacitive coupling. In another arrangement, the decoupling plate (20) is mounted be a post (21) on the end hat (15) of the magnetron cathode (1).

  • Magnetron anodes
    Publication number: 20030127987
    Abstract: In a magnetron anode, an anode (6) surrounds a central cathode (1). The anode (6) is of a segmented structure having a plurality of annular segments (9) stacked together along its length. Each annular segment (9) includes a strap (10), the strap being distributed substantially along the entire axial length of the anode vanes (8). This enables mode separation to be achieved, even for long anode lengths and hence permits high power operation to be achieved. In addition, the segmented structure of the anode gives a mechanically robust design.
