| Gyrotron has been formed a huge family, among them, the Gyrotron-TWT for itsbroadband, the characteristics of the high power output become the focus of the presentresearch to meet the need of national defense and scientific research. the inhibitorygyrotron traveling wave instability of the method is coated in a smooth waveguidedepleting substances, but this way also bring about a series of problems, first of all,graphite coating is very easy because stray electronic wait for a reason and stimulatedfall off lead to swing TWT cannot long and stable operation. Moreover, because thethermal conductivity of the graphite poor and lead to swing TWT whole tube powercapacity reduction.This article through the cyclotron TWT linear theory and nonlinear theory systemresearch the cyclotron traveling wave note-wave interaction characteristics, and on thisbasis, the cycle loading medium under the way of swing TWT note-wave interactionsimulated area, and through the optimized structure and its size to draw goodnote-wave interaction effectThis paper mainly work are as follows:1、 Understand high power microwave device swing the characteristics ofGyrotron-TWT, grasp their work theoretical basis.2、Through to the W band Gyrotron-TWT research, familiar with its development,the present situation, the application and prospect.3、Master Gyrotron-TWT note-wave interaction mechanism and high frequencystructure characteristics.4、To each part, and master the high frequency structure of the3D modelingmethods, and using Magic programming language for numerical calculation,and the result of the test and simulation results were compared. After the actualsystem for measuring and hot provide important theory basis... |
