Embodiment Construction

[0016] Below in conjunction with the accompanying drawings, taking the disk-loaded waveguide type slow-wave structure as an example, the specific implementation of the present invention will be further described. In fact, the present invention is not limited to the relativistic return wave oscillator with the disk-loaded waveguide type slow-wave structure. For relativistic return oscillators with sinusoidal or trapezoidal slow wave structures.

[0017] figure 1 Shown is a cross-sectional view of a conventional RBWO along the central axis. The traditional RBWO is composed of cathode base 1, cathode 2, anode outer cylinder 3, cut-off neck 4, slow wave structure 5, solenoid magnetic field coil 6, and the whole structure is rotationally symmetrical about the central axis. Among them, the cathode seat 1, the cathode 2, the anode outer cylinder 3, the cut-off neck 4, and the slow wave structure 5 are all made of stainless steel, and the solenoid magnetic field coil 6 is made of ena...

Abstract

The invention discloses a dielectric filled compact type relativistic backward wave oscillator and belongs to the technical field of high-power microwave. The dielectric filled compact type relativistic backward wave oscillator is rotationally symmetrical relative to the central axis and consists of a cathode seat, a cathode, an anode outer barrel, a cut-off neck, a slow wave structure and a solenoidal field coil. The slow wave structure is a disk loaded waveguide type slow wave structure and consists of five slow wave blades, wherein the inner surface of each slow wave blade is of a rectangular structure. During dielectric filling, an original structure of the RBWO is not needed to be changed, and only dielectric materials are needed to be filled among all blades of the slow wave structure. The problem that a low-frequency relativistic backward wave oscillator is too large in size and weight can be solved, and the dielectric filled compact type relativistic backward wave oscillator has wide application prospect and important scientific research value on research of small-sized compact type relativistic backward wave oscillators, promotion of engineering application process of high-power microwave systems and expansion of the RBWO application field.

Description

technical field [0001] The invention relates to a high-power microwave source, in particular to a medium-filled compact relativistic backward wave oscillator (Relativistic Backward Wave Oscillator, RBWO), belonging to the high-power microwave technical field. Background technique [0002] The Relativistic Back Wave Oscillator (RBWO) has the characteristics of high power, high efficiency and suitable for repetition frequency operation. [0003] There are three common slow-wave structures in relativistic back-wave oscillators: sinusoidal (for example, literature 1: Gao Liang, Qian Baoliang, Ge Xingjun. Particle simulation of compact P-band relativistic back-wave oscillator, strong laser and particle Beam, 2006, Vol.23, No.4), trapezoidal (such as Literature 2: Ge Xingjun, Gao Liang, Cao Yibing, etc. Preliminary Experimental Research on L-band Relativistic Back-wave Oscillator, Intense Laser and Particle Beam, 2010, Vol.22, No.3) and disk-charged waveguide type (for example, D...
