摘要: 为研究高参数等离子体的低杂波可近性,基于 HL-3 装置设计了一套位于强场侧的低杂波天线。利 用 ALOHA 代码对强场侧的天线进行模拟分析,针对只有一个单元的 PAM 天线,分别对其子波导数量、有源/无 源子波导的高度、宽度和壁厚等参数进行模拟,得到了天线的最佳结构和尺寸。最终优化后的天线发射参数为: 波谱中心的平行折射率 N||为 2.25,天线的反射系数小于 2%,方向性系数大于 0.59。

Abstract: A new lower hybrid antenna in HL-3 high field side (HFS) is designed to improve the accessibility of lower hybrid waves in high-performance plasma. The simulation of HFS lower hybrid antenna using ALOHA code is introduced. For PAM (passive active multifunction) antenna with one module, the number of waveguides and the active/passive waveguide’s height, width and thickness are simulated respectively, the optimized structure and dimension are obtained. The launching parameters of the finally optimized antenna are: the parallel refractive index of spectrum center N|| is 2.25, the reflection coefficient is less than 2%, and the directivity is greater than 0.59. 

Key words: Lower hybrid wave, HFS antenna, ALOHA code, HL-3 tokamak
