The rectangular array of magnetic probes system was newly designed and installed in the torus on J-TEXT tokamak to measure the local magnetic fields outside the last closed flux surface at a single toroidal angle. In the implementation, the experimental results agree well with the theoretical results based on the Spool model and three-dimensional numerical finite element model when the vertical field was applied. Furthermore, the measurements were successfully used as the input of EFIT code to conduct the plasma equilibrium reconstruction. The calculated Faraday rotation angle using the EFIT output is in agreement with the measured one from the three-wave polarimeter-interferometer system.
矩形阵列磁探针系统是新设计并安装在J-TEXT托卡马克装置的环形容器上的，用于在单个环向角度测量最后闭合磁通量表面外的局部磁场。在实际应用中，当施加垂直场时，实验结果与基于线轴模型和三维数值有限元模型的理论结果吻合良好。此外，这些测量结果成功地用作了EFIT程序的输入，以进行等离子体平衡重建。使用EFIT输出计算得到的法拉第旋转角与三波偏振计-干涉仪系统测量得到的结果一致。
