论文摘要
在这项工作中，采用了猎鹰代码来说明曲线融合等离子体中剪切alfvén和连续光谱的特征。猎鹰代码采用[Phys。等离子体\ TextBf {26}（8），082502（2019）]用于计算一般环形几何形状中连续光谱的全局结构。作为特定的应用，考虑了转移Tokamak测试和ASDEX升级等离子体的参考平衡。特别是，我们说明了模式极化对于识别理想MHD限制中连续光谱各个分支的物理相关性的重要性。我们还分析了血浆压缩的效果和慢速声音近似的有效性。
In this work, the FALCON code is adopted for illustrating the features of shear Alfvén and continuous spectra in toroidal fusion plasmas. The FALCON codes employs the local Floquet analysis discussed in [Phys. of Plasmas \textbf{26} (8), 082502 (2019)] for computing global structures of continuous spectra in general toroidal geometry. As particular applications, reference equilibria for the Divertor Tokamak Test and ASDEX Upgrade plasmas are considered. In particular, we illustrate the importance of mode polarization for recognizing the physical relevance of the various branches of the continuous spectra in the ideal MHD limit. We also analyze the effect of plasma compression and the validity of the slow sound approximation.
