Abstract

Abstract:

The time evolution of the emission intensity of carbon impurities is measured by an extreme ultraviolet (EUV) spectrometer in the HL-2A tokamak, and it is found that the intensity of the linear emission CIV(312.4 Å: 1s²2s-1s²3p) of C³⁺ ions obviously decreased (~10%) during the introduction of resonant magnetic perturbation (RMP). To help understand this experimental phenomenon, a simulation study of carbon impurity transport with RMP is conducted using the 3D edge plasma transport code EMC3-EIRENE. The simulation results show that under RMP perturbations of the same intensity as the experiment, the CIV intensity in the line-of sight range of the EUV spectrometer decreases (~28%), and the total impurity radiation power within the calculated region decreases (~38%), with the magnitude of the decrease depending on the intensity of the RMP perturbation.The simulation results are consistent with the experimental ones, and it is preliminarily proved that RMP will have an effect on the transport of edge carbon impurities.

摘要：

在 HL-2A 装置上利用极紫外(EUV)光谱仪测量了碳杂质辐射强度的时间演化，发现在投入共振磁扰动(RMP)期间 C ³⁺离子的线辐射 CIV(312.4 Å：1s²2s-1s²3p)的强度明显降低(~10%)。为了帮助理解这一实验现象，利用三维边缘等离子体输运程序 EMC3-EIRENE 对 RMP 下的碳杂质行为进行了模拟研究。模拟结果显示，在与实验相同强度的 RMP 扰动下，EUV 光谱仪视距范围内的 CIV 强度下降(~28%)，计算区域内总杂质辐射功率下降(~38%)，下降幅度与 RMP 扰动强度有关。模拟结果与实验结果的变化趋势吻合，初步证明了 RMP 会对边缘碳杂质的输运行为产生影响。
