摘要
HL-2A装置电子回旋共振加热的天线系统主要由天线外壳、椭球镜、平面镜、转动机构和推动机构组成.转动机构可以推动平面镜环向、极向转动,进行不同区域的等离子体的加热和电流驱动.平面镜环向转动的角度范围为0°～37°,极向转动的角度范围为0°～15°.给出了驱动杆与平面镜转动角度之间的关系和对应曲线.介绍了椭球镜的安装和推动机构的结构,给出了椭球镜的椭球面方程.整个天线系统结构紧凑,安装和拆卸容易,调节方便.
The ECRH antenna system on the HL-2A tokamak consists of shell, ellipsoidal mirror, plane mirror, rotating and pushing mechanism. The plane mirrors can be rotated toroidally and poloidally to heat plasma and drive plasma current in different regions. The variable angle ranges in toroidal and poloidal directions are 0°- 37°and 0°-15°, respectively. The relations of steering poles and steering angles are presented. The assembly of ellipsoidal mirror and the pushing mechanism are introduced. The ellipsoidal surface equation is also given. The antenna system has compact structure, and can be assembled, disassembled and adjusted conveniently.
