Automatic design and manufacturing method for relativistic backward wave tube

Abstract

The invention relates to a relativistic backward wave tube, in particular relates to an automatic design and manufacturing method for the relativistic backward wave tube, and aims to solve the problems that in the existing relativistic backward wave tube design, computer aided design is not introduced into a vacuum electronic device numerical simulation method, is only used for model three-dimensional structure display, or is limited by software universality requirements, the linear theory of the relativistic backward wave tube is not combined with a full-electromagnetic particle simulation method, and thus the design process depends on experience of researchers and the development efficiency of the relativistic backward wave tube is low. According to the automatic design and manufacturing method, a final optimization design result can be given through the method only by giving out target parameters such as the working frequency and the electron energy conversion efficiency in design indexes of the relativistic backward wave tube. Compared with a traditional relativistic backward wave tube design method depending on experience, the method achieves full automation of the design process, and the development efficiency of the relativistic backward wave tube is greatly improved.

technical field [0001] The invention relates to a relativistic return wave tube, in particular to an automatic design and manufacture method for a relativistic return wave tube. Background technique [0002] High-power microwave source device is a very complex system with many adjustable parameters. Designing an optimal device requires repeated theoretical research and experiments. Among them, the relativistic return wave tube is a very promising high-power Power microwave source device, the output electromagnetic wave power can reach gigawatt level. The process of designing the relativistic return wave tube is relatively complicated. Firstly, according to the working frequency of the relativistic return wave tube, the dispersion curve and the electronic Doppler of the relativistic return wave tube are calculated through the linear theory of the relativistic return wave tube.
