Theoretical research and simulation of 0.22 THz confocal gyrotron oscillator
摘要
Abstract
With the research of gyrotron working in millimeter wave band,the disadvantages of traditional closed circular waveguide resonator reveals more clearly. According to the gyrotron nonlinear theory,a gyrotron oscillator was designed,which adopts an open type quasi-optical resonant cavity as its HF structure. Its work frequency is 220 GHz,voltage 60 kV,current 3 A,velocity ratio 1.5 and working mode HE06. The independently developed three-dimensional particle simulation software CHIPIC is used to carry out numerical simulation,analyze its operating characteristics and optimize its parameters. The simula-tion result shows that the gyrotron oscillator can obtain 36 kW peak power output under the condition of the magnetic field of 8.57 T. The efficiency of its output power can reach 20%.关键词
