Abstract

A high-power continuous wave klystron for Tokamak device is formed by three portions: the first portion is an electronic focusing system which comprises a negative electrode, a control electrode and a positive electrode and the like, where electron beams emitted from the negative electrode are converged by the control electrode and the positive electrode, then, form a round electron beam after being subjected to high voltage acceleration, and reach a beam-wave interaction system of the klystron; the second portion is a high-frequency beam-wave interaction system of the klystron, the high-frequency beam-wave interaction system being formed by a cylindrical reentrant resonant cavity comprising an input cavity, buncher cavities and an output cavity, wherein the high-frequency beam-wave interaction system realizes improvement of power capacity, efficiency and gain effectively, and high-frequency microwave produced in the cavity is output through an output cavity waveguide; and the third portion of a collector, wherein the collector helps to collect the energy of electron beam in beam-wave interaction. The high-power continuous wave klystron is simple and easy to carry out; the high-power continuous wave klystron has the advantages of easy processing, small process processing difficulty, high efficiency and high gain and the like; and the high-power continuous wave klystron can work more stably and reliably.

Description

technical field [0001] The invention relates to the field of electric vacuum technology, in particular to a high-power continuous wave klystron for a tokamak device. Background technique [0002] With the development of the economy and the improvement of living standards, the human demand for energy is increasing day by day. At present, the energy used by humans is mainly fossil fuels, as well as fission nuclear energy and renewable energy. The greenhouse effect caused by the extensive use of fossil energy and its pollution to the atmosphere, soil and water, and the use of fission nuclear energy will produce a large amount of radiation and safety hazards, and even bring disastrous consequences to the world environment. [0003] The use of controllable thermonuclear fusion can realize the generation of clean energy, and it has no radiation, can work safely, and has no destructive impact on the human environment. But thermonuclear fusion reactions require temperatures of hun...
