摘要： A microwave magnetron-type device comprises at least one anode block with annular metal straps electrically associated with respective vanes of the anode block cavities, having the same polarity at -mode. The straps of different polarities, electrically associating respective vanes of the same polarity, are paired, each pair being arranged with respect to one another along the anode block axis to form a single multistage retardation system. The device also comprises a means for creating a magnetic field directed along the anode block axis enveloping said anode block, and a means for increasing the magnetic field density in direct proximity to the anode block end faces, forming a gap with the end faces of the anode block. At least some of said straps are made at least partically of a magnetic material, and the mass of this material is so distributed along the anode block axis that the magnetic field density varies along the anode block axis as follows: ##EQU1## where B.sub.x is the variation in the magnetic field density along the anode block axis;B.sub.O is a constant component of the homogeneous magnetic field density along the anode block axis;B.sub.O1 is the amplitude of variation in the magnetic field density along the anode block axis, over its length X.sub.1, which does not exceed 50% of B.sub.O ;B.sub.O2 is the amplitude of fluctuation of the magnetic field density from one pair of retardation system straps to another along the anode block axis, over its length X.sub.1, which does not exceed 20% of B.sub.O ;h is the spacing between strap pairs;n=1,2,3 . . . is a coefficient equal to the number of half-cycles of the cosinusoidal distribution of the amplitude of the high-frequency electric field of a respective mode.

摘要： A microwave device of the magnetron type comprises an anode block with straps which are located with respect to one another along the axis of the block and are electrically connected to respective vanes of resonators of the block, these vanes having like polarity at the .pi.-mode of oscillations. The anode block is provided with cooling channels adapted to cool the vanes of the resonators and straps, said channels communicating with at least one chamber designed to distribute a liquid coolant and with at least one chamber designed to collect the liquid coolant, said chambers being rigidly connected with the anode block and provided with a hydraulic coupling between them. The straps of the anode block are implemented in the form of ring-like tubes. At least four vanes, connected with the corresponding ring-like tubes, are provided, each, with radially extending channels equal in number to the ring-like tubes which are connected with these vanes, the channels each communicating with a respective one of the ring-like tubes and serving together with the tubes as the cooling channels for respective vanes and straps. One of the radially extending channels, communicating with a respective ring-like tube, also has a communication with the coolant distribution chamber, while another radially extending channel communicates with the coolant collection chamber. The chambers are located along the axis of the anode block and each has a length, as measured in the direction of that axis, equal to at least a space between two outermost radially extending channels which communicate with respective chambers.
