A multi-voltage probe array system is designed to measure the coupling resistance of an ion cyclotron resonance frequency antenna. In the process of the antenna coupling resistance data extraction, the minimization algorithm, the original Levenberg–Marquardt algorithm, is replaced by the Broyden–Fletcher–Goldfarb–Shanno algorithm to achieve more stable and accurate results. Moreover, a simple model of the multi-voltage probe array was applied to simulate the performance of the Kalman filter, and to optimize the distance and position of the probes and probe number to mitigate the influence of the system noise on the rebuilt results. During the EAST experiment in 2019, a four-voltage probe array was applied to measure the coupling resistance of line 6 during high confined mode discharge. The measurement results by the multi-voltage probe array system and the voltage/current probe pair show a good agreement.

用于在EAST上测量ICRF天线耦合电阻的多电压探针系统的设计

设计了一种多电压探针阵列系统，以测量离子回旋共振频率天线的耦合电阻。在天线耦合电阻数据提取过程中，最小化算法（最初的Levenberg-Marquardt算法）被Broyden-Fletcher-Goldfarb-Shanno算法代替，以实现更稳定，更准确的结果。此外，采用了多电压探头阵列的简单模型来模拟卡尔曼滤波器的性能，并优化了探头的距离和位置以及探头的数量，以减轻系统噪声对重建结果的影响。在2019年的EAST实验中，采用了四电压探头阵列来测量高约束模式放电期间6号线的耦合电阻。
