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.
Claims19
A magnetron anode comprising a plurality of stacked segments joined together to define anode vanes, each of the segments including a strap and portions of the anode vanes, each segment comprising a ring from which extend portions at intervals inwardly and outwardly in a radial direction which form parts of the anode vanes, the straps being distributed substantially uniformly spaced along an axial length of the anode vanes.
A method of manufacturing a magnetron anode comprising steps of forming annular segments, each segment including portions of anode vanes, each segment comprising a continuous ring from which extend portions at intervals inwardly and outwardly in a radial direction which form parts of the anode vanes;
- stacking the annular segments;
- and then joining the stacked segments together.
A magnetron including a cathode coaxially surrounded by a magnetron anode, the anode comprising a plurality of stacked segments joined together to define anode vanes, each of the segments including a strap and portions of the anode vanes, each segment comprising a ring from which extend portions at intervals inwardly and outwardly in a radial direction which form parts of the anode vanes, the straps being distributed substantially uniformly spaced along an axial length of the anode vanes.
