Characteristics of main configurations of Wendelstein 7-X

Abstract

For nine main magnetic configurations of Wendelstein 7-X the vacuum magnetic fields, Fourier coefficients, rotational transform profile, magnetic well, helical and effective helical ripple values are computed and results of modeling are available now for general use [1]. The influence of the shaping of the pressure profile on the plasma equilibrium and stability properties has been investigated for the Standard case, <b>=4%. Simulation has shown that the edge region is almost independent of the pressure profile, while plasma properties inside the last closed magnetic surface (LCMS) are considerably changed.
