In the divertor magnetic configuration, the kinetic stability analysis taken into account an ion Larmor gyration is carried out. This is because the divertor magnetic configuration has the null point, where the Larmor radius grows near the region of the null point. Therefore the MHD approximation is not appropriate for the divertor magnetic configuration.
A kinetic stability analysis equation is derived by Y.Sasagawa et al. and which takes into account the anisotropic temperature and its radial dependence. Using this equation, we investigate the stability boundary of flute interchange mode for GAMMA10 central cell divertor.
