论文摘要
恒星作为磁性限制融合的概念需要仔细的设计才能有效地局限粒子。设计的可能性是为磁场配备称为准对称的特性。尽管通常认为稳态的准对称平衡只能在局部确切(除非系统具有连续对称的方向,例如Tokamak),但我们建议在这项工作中,平衡范式的变化可以改善此限制。我们证明,与各向异性压力之间存在甲合压对称性和磁平衡之间存在深厚的物理联系,从而超出了通常考虑的各向同性压力平衡。
The stellarator as a concept of magnetic confinement fusion requires careful design to confine particles effectively. A design possibility is to equip the magnetic field with a property known as quasisymmetry. Though it is generally believed that a steady-state quasisymmetric equilibrium can only be exact locally (unless the system has a direction of continuous symmetry such as the tokamak), we suggest in this work that a change in the equilibrium paradigm can ameliorate this limitation. We demonstrate that there exists a deep physical connection between quasisymmetry and magnetostatic equilibria with anisotropic pressure, extending beyond the isotropic pressure equilibria commonly considered.
