Mechanical frequency control in a klystron tube comprising a directly attached rectangular cavity resonator

Claim 1

AN ARRANGEMENT FOR EFFECTING THE FINE MECHANICAL RUNING OF DIRECTLY MODULATED KLYSTRONS COMPRISING AN ATTACHED RECTANGULAR CAVITY RESONATOR AND AN OUTPUT COUPLING DIAPHRAGM, FIRST COARSE FREQUENCY TUNING MEANS POSITIONED IN SAID CAVITY FOR ADJUSTMENT IN A PARALLEL RELATION WITH RESPECT TO THE ELECTRIC FIELD THEREIN, SECOND FINE FREQUENCY TUNING MEANS FOR ADJUSTING THE RESONANT FREQUENCY OF THE KLYSTRON RESONATOR INCLUDING A BAR OF NONCONDUCTING MATERIAL HAVING A HIGH DIELECTRIC CONSTANT POSITIONED TRANSVERSELY OF SAID ELECTRIC FIELD AND HAVING ONE END PROJECTING AXIALLY INTO THE CAVITY THROUGH SAID COUPLING DIAPHRAGM AT A POSITION BELOW AND ADJACENT SAID FIRST TUNING MEANS, THE FREQUENCY VARIATION BEING DEPENDENT UPON THE DISTANCE SAID BAR PROJECTS THEREIN FROM SAID DIAPHRAGM, AND OUTPUT MEANS RECEIVING ENERGY FROM SAID RESONATOR, SAID BAR BEING SLIDABLY ARRANGED AND SUPPORTED AT ANOTHER PORTION IN A WALL OF SAID OUTPUT MEANS LYING OUTSIDE THE RESONATOR.
