- Аннотация: The growth rates of the ideal MHD stability of the plasma equilibrium configurations in the Trimyx Galatea trap with current-carrying conductors immersed in plasma are calculated. The unstructured grid ideal MHD stability code MHD_NX was upgraded to take into account plasma compressibility. The stability limits of the pressure magnitude in the Trimyx plasma are computed with plasma boundary cut-off from the vacuum vessel. The computed pressure limits are compatible with the experimental data [8]. The extension of plasma beyond the Ohkawa surface in the experiment can be explained by the compressional stabilization of the flute modes with a possible relation of both the plasma boundary extent and the pressure magnitude to the limiting finite- MHD modes.
