Abstract
The invention concerns a resonant cavity magnetron employing a strapped vane anode (4, 9, 11, 13, 15) structure. In order to compensate for thermal variations at least one of the straps (13) is made from a material or materials having a different temperature coefficient of linear expansion to the vanes (4) such that the strap (13) will deform with temperature variation in a predictable manner to modify the resonant frequency of the magnetron.
