MHD plasma stability of plasmas in Galatea traps was calculated using the equilibrium and stability codes for axisymmetric configurations on unstructured computational grids. For equilibrium configurations in the Trimix magnetic trap the dependence of the growth rates of ideal MHD modes with different toroidal wave numbers on the pressure magnitude was investigated.
