论文摘要
在低纵横比（R/A = 2）的实验测量的单个螺旋状态已与圆柱弛豫理论的预测进行了比较，并且在某些宏观特征方面存在很大的偏差，尤其是对于与大型边缘环形场相对应的情况。在本文中，我们通过采用VMEC和宽松平衡代码来考虑环形几何形状的效果。我们表明，包含环形性会为圆柱状状态产生重大校正，尤其是对于深层逆转的情况。
The experimentally measured single helical states in the low aspect ratio (R/a=2) RELAX device have been compared with the predictions of a cylindrical relaxation theory and a substantial deviation in terms of some macroscopic characteristics has been found, in particular for cases corresponding to a large reversal of the edge toroidal field. In this paper we consider the effect of the toroidal geometry by employing the VMEC and the RelaxFit equilibrium codes. We show that the inclusion of toroidicity produces significant corrections to the cylindrical states, especially for the deep reversed cases.
