摘　　要：电子回旋共振加热(Electron Cyclotron Resonance Heating,ECRH)系统是中国环流三号(HL-3)实验装置的一种重要加热和等离子体电流控制方法,微波通过天线发射器注入等离子体,是ECRH系统的重要组成部分。根据ECRH系统需求,对其天线系统进行了概念设计和光路设计以及具体的天线制作,并进行了测试与安装。HL-3装置ECRH天线系统由三个天线组成,包含一个中平面天线和两个上斜天线,三个天线位于装置弱场侧的同一扇段,可协同完成加热、新经典撕裂模(Neoclassical Tearing Mode,NTM)控制等功能。目前已经完成其中两个天线的设计、制造和测试,另外一个天线完成了发射光路的设计。测试结果表明:中平面天线和上斜一号天线控制精确、快速,达到了装置实验使用的要求。[Background]Electron cyclotron resonance heating(ECRH)is an important heating and plasma current control method for the HL-3 tokamak.Microwave inject into plasma through the launcher,which is an important part of the ECRH system.The ECRH launcher system of HL-3 tokamak consists of three launchers,including a mid equatorial launcher and two upper launchers.All launchers are located in the same sector,and can work together to complete functions such as heating and Neoclassical Tearing Mode(NTM)control.[Purpose]This study aims to design and test the ECRH launcher system of the HL-3 tokamak.[Methods]First of all,the overall planning was carried out for the launcher system.Subsequently,the transmission path and structure of the launcher were designed,and the effect of microwave injection were calculated by simulation.Then,detail design and implementation for the mid-equatorial launcher and No.1 upper launcher were completed,so did the optical path design for No.2 upper launcher.Finally,the transmission angle and rotation speed of the launcher were tested,and the rotation angle of the launcher was calibrated.[Results]The full range response time of the mid-equatorial launcher is less than 90 ms.The full range response time of the No.1 upper launcher is less than 190 ms.[Conclusions]The control of the equatorial launcher and the No.1 upper launcher is precise and fast,meeting the requirements for experimental use of the tokamak.
