摘要:

利用毕奥萨伐尔定律,通过对EAST内部等离子体电流的运动状态的研究,建立了EAST内部的磁场数学模型,并利用Matlab对实验数据的拟合分析,对模型进行了分析验证。通过误差分析,进而改进模型,研究表明改进后的模型与实验数据能较好吻合,误差较小。相关研究和结论对托卡马克真空室内磁场测量具有一定的指导意义,为进一步研究基于MEMS技术的超导托卡马克装置电磁测量诊断系统的微纳磁敏传感器奠定理论基础。

Abstract:

Based on Biot-Savart law, through learning the internal EAST plasma current state of motion, establishing the mathematical model of magnetic field inside EAST, simulating and analyzing the experimental data by Matlab, the model is analyzed and verified. Through error analysis, the model is improved, and studies show that improved model fit well with the experimental data, the error is small. Meanwhile related research and conclusions have some significance for measuring the magnetic field of tokamak vacuum chamber, it provides the theoretical basis for MEMS magnetic sensor on electromagnetic measurement system of superconducting tokamak.
