Description
Technical Field
The invention belongs to the technical field of microwaves, and particularly relates to an axial cascade relativistic magnetron based on a frequency locking phase locking of a ring-rod coupling structure.
Background
From the perspective of practical high-power microwave systems, the development of high-power microwave systems mainly focuses on the following aspects: (1) the system is miniaturized and compacted, and the power consumption ratio is improved; (2) high repetition frequency operation; (3) the frequency can be tuned; (4) outputting in multiple frequencies; (5) and (4) synthesizing the output of the phase-locked array and the power. Since its birth, the relativistic magnetron has been receiving attention due to its compactness and high efficiency. In order to meet the development and application requirements of future high-power microwave sources, a relativistic magnetron with the characteristics of high output power, high conversion efficiency, suitability for long-pulse and high-repetition-frequency operation, frequency-locking phase-locking multiport output and the like becomes an important research target of people.
Classified according to the topology, there are 3 types of relativistic magnetron phase-locking methods proposed at present, which are allelic phase-locking, injection phase-locking, and cascade phase-locking, respectively. In 1989, the relativistic magnetron of allelic phase locking was proposed by the company James N.Benford, U.S. Physics International, and the output ports of 2A 6 relativistic magnetrons placed in parallel were connected by rectangular waveguides to realize locking, and the other ports were used for microwave output, and the output power of about 3GW was obtained under the condition that the two magnetrons work together. In 1991, Todd A.Treado et al, Varian Associates, Inc. in the United states, proposed a relativistic magnetron with injection phase locking, and it was experimentally determined that the relativistic magnetron can generate 52MW output power under the condition of phase locking by injecting power to one port of the relativistic magnetron with an S-band 3MW coaxial magnetron. In 1992, General Dynamics group Keith g.kato et al, usa proposed a relativistic magnetron with cascade phase locking, where anodes of 4 eight-cavity magnetrons were arranged at equal intervals in the axial direction, and corresponding cathodes in the respective tubes were connected into one body, and it was intended to obtain output power with a total of more than 1GW at 16 output ports. In 2015, Andrey d.andreev, Raytheon, usa proposed a slot-type conventional magnetron that implemented cascade locking using an axial spacer strip to connect the anode blocks of adjacent magnetrons.
When a plurality of relativistic magnetrons are arranged in a cascade manner, a strong current which is several times of the working current of a single magnetron flows through a cathode rod close to one end of an accelerator, an angular induction magnetic field with amplitude which is similar to that of an axially applied magnetic field is caused in an injection-wave interaction region, and further, the axial drift of electrons, the jump of a working mode, the frequency shift effect and the pulse shortening effect are caused, so that the frequency locking and phase locking of the cascade relativistic magnetron fails.
The coupling mode of the currently proposed cascaded phase-locking scheme is single, the cascaded phase-locking relativistic magnetron realizes high-frequency electromagnetic field interaction mainly by drawing the distance between adjacent magnetrons, and the cascaded phase-locking conventional power magnetron realizes electric coupling by conducting anode blocks in the adjacent magnetrons by using an axial mode isolation belt, and the two schemes still have more limitations in practical application.
The structural characteristics of the resonance system can be changed by shortening the distance between the adjacent anode blocks, so that the coupling impedance of each intrinsic mode of the magnetron is changed, the working area of the expected working mode of the magnetron is easily narrowed, a certain electronic tuning range is lost, higher requirements on the regulation and control precision of an external anode voltage and an external axial magnetic field are provided, and the practicability of the magnetron is reduced. Meanwhile, the axial distance between adjacent magnetron extraction channels is too small, so that the structural design difficulty is improved, and the layout flexibility is reduced.
The design scheme of the axial diaphragm band has good operation effect in the cascade conventional power magnetron, but the ideal working state is difficult to achieve in the cascade relativistic magnetron. The strong current flowing through the cathode of the cascade relativistic magnetron causes a strong angular induced magnetic field in the injection-wave interaction region between the cathode and the anode, and the strong angular induced magnetic field and the radial electric field between the cathode and the anode jointly push electrons to do axial drift motion, so that the electron density distribution in each interaction region of the cascade magnetron is unbalanced, and further the output power difference of each tube is overlarge. The strong angular electric field has a higher harmonic mode which is easy to excite and has a larger difference with the working frequency point of the fundamental mode. Phase locking is difficult to achieve with only conventional diaphragm band structures.
