Description

The effective numerical code to study the tearing modes in toroidal geometry for noncircular cross-section plasmas is proposed. It is found that the stabilization of n=1 mode for particular q profile with q'=0 on the q=1 surface depends on the elongation of q=2 resonant surface. A new effective method is proposed for study of the non-linear plasma evolution in tokamak. (author) 2 refs., 2 figs
