论文摘要
在这项工作中，我们演示了一种使用外部多型磁场线圈包围的任何给定的2D形状的Solov'EV平衡的方法。计算结构域由两个部分组成：等离子区域，其中解决方案与Solov'EV溶液相同，以及真空区，其中外部线圈产生的磁场以及血浆电流是通过绿色函数方法通过SAPAINATRIX附近的匹配条件确定的。但是，该方法不仅限于Solov'EV平衡。这种方案的准确性，效率和鲁棒性表明，使用外部线圈，可以将该方法应用于带有真空区域的Tokamak等离子体的2D形状。
In this work, we demonstrate a method for constructing the Solov'ev equilibrium with any given 2D shape surrounded by a vacuum region using external poloidal field coils. The computational domain consists of two parts: the plasma region, where the solution is the same as the Solov'ev solution, and the vacuum region, where the magnetic field generated by external coils as well as plasma current is determined using the Green function method through a matching condition near the separatrix. However, the method is not limited to the Solov'ev equilibrium in particular. The accuracy, efficiency, and robustness of such a scheme suggest that this method may be applied to the 2D shaping of tokamak plasma with vacuum region using external coils in general.
