摘要
研究了在小环径比托卡马克系统中的竖直位移不稳定性,探讨了椭圆拉长与装置的环径比、磁面位形三角形变的关系。计算得出,在小环径比条件下,允许等离子体位形有较大的椭圆拉长。同时发现,当环径比A≤2时,允许的椭圆拉长反而减小。对于给定的磁面函数,我们还推导出环径比和三角形变有一定的制约关系。
おe mainly study the vertical displacement instability in a lowaspectratio tokamak, and discuss the relation between aspectratio and elongation. For lowaspectratio tokamaks, it is possible for the magnetic flux surface to have a larger elongation. Meanwhile, we also find that the elongation will tend to reduce when A≤2, and the range of the triangular deformation parameter and the aspectratio of tokamak are subject to certain restrictions.
