Abstract
A tunable, coaxial-vacuum magnetron is shown having a cathode surrounded by an anode within a surrounding evacuated anode cavity. Located between the cathode-anode interaction space and an output from the anode cavity is a tuning mechanism which includes a single symmetrical ceramic tuning rod that is adjusted along its axis into and out of the anode cavity. The adjustment mechanism includes a tuning nut rotatably mounted in a tuning housing which turns to move a threaded shaft along the axis thereof. Separating the threaded shaft from the anode cavity is a bellows attached to the tuning housing and to which is attached the symmetrical tuning rod for sealing the vacuum cavity.
