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.
Claims26
A magnetron anode comprising a plurality of stacked segments joined together to define anode vanes.
An anode as claimed in any preceding claim and including a plurality of straps.
An anode as claimed in any preceding claim wherein each segment includes portions of half the total number of anode vanes and adjacent segments are arranged such that the portions of the anode vanes are interleaved.
An anode as claimed in any preceding claim wherein the segments are nominally identical in form.
A method of manufacturing a magnetron anode comprising the steps of:
- forming annular segments, each segment including portions of anode vanes;
- stacking the annular segments;
- and then joining the stacked segments together.
A magnetron anode substantially as illustrated in and described with reference to the accompanying drawings.
A magnetron including an anode substantially as illustrated in and described with reference to the accompanying drawings.
A method of manufacturing a magnetron anode substantially as illustrated in and described with reference to the accompanying drawings.
