摘要
为准确测量等离子体放电期间离子回旋加热天线输入阻抗以及同轴传输线的驻波电压和电流,建立了基于探针阵列、LabVIEW数据采集及分析的天线阻抗测量系统;采用非线性曲线拟合的方法计算天线输入阻抗及驻波电压、电流和输入功率;将计算结果与定向耦合器的测量数据进行对比,验证阻抗测量的精度。
In order to accurately measure the ICRH antenna impedance, as well as the voltage and current of standing waves along the transmission line during plasma discharge, a new impedance measurement system based on probe - array, data acquisition and analysis by LabVIEW has been developed. In this paper, the input antenna impedance, as well as the voltage, current and input power of standing waves, were calculated using non - linear curve fitting method. The precision of impedance measurement was proved by the way of contrasting the calculation results with the measurement data by directional coupler.
