摘要
HL-2A装置1MW/68GHz/1s电子回旋共振加热传输系统有两条传输线,每条传输线包括波纹波导、换向波导和直流隔离器。HE11模式微波在波导中传输,微波损失小且模式纯度高。用激光校准及用热敏纸测量短脉冲微波模式分布的手段确保传输线的准直性。传输线的倾斜角度小于0.0054rad。
The transmission system of 1MW/68GHz/1s ECRH for the HL-2A tokamak includes two transmission lines. Each line consists of corrugated waveguide, miter bends and a DC break, in which the HE11 mode waves propagate with low loss and high mode purity. In order to align the lines, laser was used firstly and then the mode distribution of short pulse wave was measured by means of thermo-paper. The tilt angle is less,than 0.0054rad.
