论文摘要
在这项研究中研究了具有不同移流构型的壁回收的特征，重点是观察Balmer系列中氘原子排放的空间分布（D_α，D_β，D_γ和D_δ）在实验性先进的超导管托卡马克中具有不同的磁场配置。观察到的D_α和D_β的发射主要接近分离靶标，而D_γ和D_Δ排放的主要接近X点。靠近分流目标和X点的排放分布根据分离构型而发生了不同。这些实验结果表明，基于不同配置中轮廓形状相似性的参数的线性比较不足以理解分离等离子体中的粒子回收。这是因为当磁性构型改变时，回收的氘原子的密度曲线的形状和/或电子密度和温度可能会发生变化。
The characteristics of wall recycling with different divertor configurations were investigated in this study, focusing on the observations of the spatial distributions of deuterium atomic emissions in the Balmer series (D_α, D_β, D_γ, and D_δ) with different magnetic field configurations in the Experimental Advanced Superconducting Tokamak. The observed D_α and D_β emissions were primarily relatively close to the divertor targets, while the D_γ and D_δ emissions were primarily relatively close to the X-point. The distributions of the emissions close to the divertor targets and X-point changed differently depending on the divertor configuration. These experimental results indicate that the linear comparison of parameters based on an assumption of similarity of profile shapes in different configurations is insufficient for understanding particle recycling in divertor plasmas. This is because the shape of the density profile of the recycled deuterium atoms and/or the electron density and temperature may change when the magnetic configuration is altered.
