A set of magnetic diagnostics has been designed, manufactured, and calibrated for the first operational phase of the small aspect ratio tokamak. The sensor suite comprises of Rogowski coils; 2D magnetic probes; and poloidal, saddle, and diamagnetic flux loops. A set of continuous Rogowski coils has been manufactured for the measurement of plasma current and induced eddy currents in conductive elements. A set of flux loops and magnetic probes will be used as input for the reconstruction of the magnetohydrodynamic equilibrium. The quantity and position of these sensors have been verified to be sufficient with synthetic equilibrium reconstructions using the equilibrium fitting code and baseline scenarios computed with the Fiesta code. These sensors will also be used as input for the real-time control system, and magnetic probes will be used for the detection of plasma instabilities. The calibration procedure for the magnetic probes is described, and the results are shown. The signal conditioning and data acquisition systems are described.
已为小纵横比托卡马克的首个运行阶段设计、制造并校准了一套磁诊断设备。该传感器套件包括罗果夫斯基线圈、二维磁探针以及极向、鞍形和抗磁通量环。已制造出一组连续罗果夫斯基线圈,用于测量等离子体电流和导电元件中的感应涡流。一组通量环和磁探针将用作磁流体动力学平衡重建的输入。利用平衡拟合代码和用Fiesta代码计算的基线情景,通过合成平衡重建已验证这些传感器的数量和位置是足够的。这些传感器还将用作实时控制系统的输入,并且磁探针将用于检测等离子体不稳定性。描述了磁探针的校准程序并展示了结果。还描述了信号调节和数据采集系统。
