Abstract:

To decide the allowable error range of magnetic measurement system, it is assumed that the measurement errors of the magnetic probe and flux loop signals are characterized by a normal probability distribution on HL-2M. The input signals with errors are calculated using the EFIT code in fitting mode. The analysis results show that the good plasma configuration can be obtained if the measurement errors are lower than 4%.

摘要：

为判断HL-2M磁测量系统信号允许的误差范围，假设HL-2M装置上磁探针和磁通环的测量值误差服从正态概率分布，采用EFIT程序对有误差的输入信号进行了反演运算。分析结果表明，把测量误差控制在4%以内，EFIT反演运算能够得到较好的等离子体位形。
