| 摘 要： | 介绍了离子回旋波加热中天线的研究进展，讨论了传统环天线、相控双环天线及双臂单环天线激发波的频谱特征。使用射线轨迹方法对单通吸收率进行了数值计算，得到环向谱与单通吸收率的关系。由此验证了双臂单环天线有较好的耦合性能。该天线结构简单，能够改善加热性能。

| Abstract: | The progress of research on the antenna system ion cyclotron wave heating is presented, and the spectrum characters of conventional loop antenna, phase controllable double loop antennae and double limb single loop antenna are discussed. The single pass absorption rate is studied by digital simulation of ray tracing scheme, and the relation between single pass absorption rate and toroidal spectrum is obtained. In this way, it is verified for the double limb single loop antenna to have good coupling performance. This antenna’s structure is simple and can be used to improve coupling performance. |
