ABSTRACT:
The present invention concerns a rising sun magnetron comprising an anode ring having a series of radially inwardly-projecting teeth-like elements of a relatively high thermal coefficient of expansion. Each element (27) has a vane (21) of material of relatively low thermal coefficient of expansion secured on either side thereof so as to define alternate long and short cavities and an associated length of material (26) also of low coefficient of thermal expansion lying between the adjacent pair of vanes (21) and acting as a fulcrum for the associated vanes when the element (27) expands due to temperature rises.
