The first EMC3‐EIRENE modelling for the JT‐60SA edge plasmas with/without the resonant magnetic perturbation field (RMP) was conducted. Both core degradation in the vacuum approximation and strike‐point splitting were observed due to the application of the RMP, as in previous studies in other devices. Toroidally averaged divertor heat fluxes with and without the RMP were fitted by using a one‐dimensional diffusive model function, showing similar profiles. To extract the modulation components of the divertor heat flux profile, the proper orthogonal decomposition (POD) method was applied. By using the POD outputs, a modulation ratio with respect to the toroidally averaged profile was quantitatively calculated.

带有/不带有共振磁扰动场的JT-60SA边缘等离子体的首次EMC3-EIRENE建模

对具有/不具有共振磁扰动场（RMP）的JT-60SA边缘等离子体进行了第一个EMC3-EIRENE建模。如先前在其他设备中的研究一样，由于RMP的应用，在真空逼近和触击点分裂中都观察到了堆芯退化。通过使用一维扩散模型函数拟合具有和不具有RMP的环形平均偏滤器热通量，显示出相似的轮廓。为了提取偏滤器热通量分布的调制分量，应用了适当的正交分解（POD）方法。通过使用POD输出，定量计算相对于环形平均轮廓的调制比。
