| 摘 要： | 68GHz ECRH系统由6套0.5MW/1s(1.5s)子系统构成，140GHz ECRH系统由2套1MW/3s子系统构成。每套子系统由独立的传输线与天线相连，再通过天线注入等离子体。68GHz ECRH子系统为非真空传输线，以内径为80mm的过模波纹圆波导为主要传输部件，包括隔直器、弹性波导、换向波导和一个槽纹深度为l/2的极化器；140GHz ECRH子系统为真空传输线，以内径为63.5mm的过模波纹圆波导为主要传输部件，包括隔直器、弹性波导、换向波导、转换开关、抽气波导和槽纹深度分别为l/4与l/8的极化器。经过不断地完善，68GHz ECRH系统传输线已成功运用于ECRH运行中，整条传输线的输送效率可以达到90%左右。对于140GHz ECRH系统，已完成了传输部件的整体设计，目前正在进行相关部件加工测试。

| Abstract: | The 68GHz ECRH system consists of the 6 sets of 0.5MW/1s (1.5s) sub system, and the 140GHz ECRH system consists of the 2 sets of 1MW/3s sub system. Each sub system is connected with the transmission line by the antenna independently. The 68GHz ECRH system has non-vacuum transmission line that the main component is the over mode corrugated circular waveguide with the inner diameter of 80mm. The 140GHz ECRH system has vacuum transmission line that the main component is the over mode corrugated circular waveguide with the inner diameter of 63.5mm. The 68GHz ECRH system has been used for ECRH discharges successfully and the transmission efficiency can reach 90%. For the 140GHz ECRH system, the transmission line has been designed completely. |
