摘要： A magnetron with a central cathode coaxially surrounded by an annular anode forming an array of cylindrical resonant cavities is tunable by an axially movable disk carrying hollow plungers which project into these cylinders, the disk being spacedly overlain by a lid or wall member defining therewith a shallow chamber for the circulation of a cooling fluid. The fluid enters and leaves via expandable inlet and outlet channels to traverse not only the chamber but also the interior of the several plungers. The axial adjustment of the disk is brought about by rotation of a ring with an internally threaded hub engaging a complementarily threaded hollow boss rigid with the disk, the chamber communicating with the interior of the boss through peripheral apertures of the latter. The fluid is branched off a hydraulic circuit for the cooling of the stationary electrode structure formed by the anode and the cathode.
