Abstract
701,925. Magnetrons. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 28, 1951 [April 3, 1950], No. 7203/51. Class 39(1) A magnetron comprising a cathode and a concentric anode block including a number of resonant cavities 1 is characterized. in that it includes an auxiliary tuning cavity 5 coupled symmetrically to some of the anode cavities, the tuning cavity being provided with means for varying its geometrical size to tune the magnetron. As shown in Figs. 1 and 2A the auxiliary cavity 5 may surround the anode block, alternate cavities being coupled to it through slots 2; the cavity is provided with an aperture 6 to couple it to a load circuit and is tuned by a piston 7 fixed to a flexible membrane 8. Anode straps are unnecessary if the impedances of the coupling slots 2 and the impedance of the cavity 5 are correctly designed. In a modification, Fig. 4, the auxiliary cavity 5 is at the end of the anode cavities; alternate anode cavities may be closed at their ends so that they do not communicate with the cavity 5.
