摘要
给出了用于HT 7超导托卡马克聚变实验装置的电子回旋共振加热 (ECRH)系统大功率毫米波传输线的设计 .该传输线将回旋管输出的频率为 6 0GHz ,峰值功率 2 0 0KW ,脉冲宽度不大于 10 0ms的毫米波传输数十米 .在传输过程中将最初的TE0 2 波转换为TE0 1波 ,再进一步转换至准线性TE11波 ,最终通过准光学天线将该毫米波以一定的角度发射到托卡马克等离子体中 .
The design of the high-power millimeter-wave transmission line for Electron Cyclotron Resonance Heating (E-CRH) system on the HT-7 Tokamak was given. The waves output from the gyrotron with peak power of NOW, frequency 60GHz and pulse length around 100ms was transmitted for several tens of meters through this line. In the transmission process, the wave's mode was converted from initial TE02-mode to TE01 and then to the semi-linear TE11-mode by two-mode converter. In the end of the transmission line, the wave was coupled to the semi-optical antenna and then was launched into plasmas along a special angle.
