PURPOSE:To increase the dimensional accuracy of a magnetron anode structure and facilitate its assembly by using strap rings having the same or similar shapes to connect an even number of vanes installed in an anode cylinder constituting a resonant cavity. CONSTITUTION:A magnetron anode structure 1 is constituted of an anode cylinder 1a constituting a resonant cavity, an even number of vanes 21 radially arranged inside the cylinder 1a and two strap rings 40 for connecting the vanes 21. During assembly of the magnetron anode structure 1, strap rings 31 and 41 are compulsorily pressed into the groove 21a of the vane 21 at a given interval. By the means mentioned above, the magnetron anode structure 1 can be produced by making the positions of a few strap rings having the same or similar shapes different. Consequently, it is possible to increase the thermal stress resistance of the magnetron anode structure 1 and to facilitate its assembly. |
