| 摘 要： | 为了提高HT-7装置上等离子体电子回旋辐射(ECE)超外差诊断系统的极向分辨率，根据高斯光学原理，分析了诊断系统天线的改进方案。优化了天线的圆形角锥喇叭尺寸和凸透镜参数以及在装置上的相对位置，使天线接收到的等离子体ECE异常模二次谐波辐射的高斯光束束半径只有30mm左右，能量的高斯光学性质损失不大于13%。

| Abstract: | A scheme for redesigning its antenna in Gaussian optics is presented for improving the poloidal spatial resolution of the plasma electron cyclotron emission (ECE) super-heterodyne radiometer diagnostic system on the HT-7 tokamak. It is shown that the Gaussian optic loss of the radiant energy from the plasma ECE is no more than 13% by optimizing the dimensions of the circular pyramidal horn,the focus of the convex lens of the antenna system and their relative positions when the Gaussian bean radius of the emission of the ECE novel second harmonic is only 30mm or so. |
