| 摘 要： | 为了获得精准的磁场测量数据，基于磁探针测量磁场的基本原理，构建了由长螺线管、交流电源、标准探针和数据采集系统组成的长螺线管标定系统，对EAST 磁探针垂直于磁感应强度方向的总有效面积(NS 值) 进行了精确的标定，并对标定数据进行了分析处理。获得的结果符合预期的误差要求，为磁探针精确测量托卡马克中的磁场提供了前提条件。

| Abstract: | Based on the basic principle of measuring magnetic field by magnetic probe, a solenoid calibration system is constructed by a long solenoid, alternating current power, standard probe and data acquisition system in order to get the accurate magnetic field data. The NS value of magnetic probe on EAST is calibrated accurately by the solenoid calibration system and the data of the calibration is analysed. The obtained results are what we expected and provide the prerequisite for accurate magnetic field measurement in tokamak. |
