| 摘 要： | 在225 GHz回旋管同轴输出腔结构特性的基础上,采用三维电磁软件给出了输出腔后同轴输出结构的设计。数值模拟了内轴不同半径和截断长度对传输效率和带宽的影响,并由此设计出中心频率225 GHz、传输效率为96.2%、带宽接近4GHz的同轴输出结构。

| Abstract: | On the basis of structure characteristics of 225 GHz Gyrotron cavity,the coaxial output structure following the output cavity was designed by using three-dimensional electromagnetic code in this paper.The effects of different inner axis radius and the cutting length on transmission efficiencies and bandwidth were numerically simulated,and this result contributes to the design of coaxial outpul structure in the center frequency of 225 GHz,with its transmission efficient of 96.2%,and bandwidth near to 4 GHz. |
