Calculation of quasispherical liner compression of a compact toroid

One of possible liner thermonuclear systems is a scheme in which quasispherical compression by the compact plasma toroid shell is used. On the basis of a developed technique of numerical calculation of equilibrium magnetic configurations the evolution of a compact toroid at the variation of a volume and cavity form up to practically important values of compression degree K=1000 under which thermonuclear plasma parameters can be obtained is investigated.. The algorithm of axial symmetrical magnetic configurations based on minimization of total energy of discrete model plasma-magnetic field on mixed Eiler-Lagrange variables is used. It is shown that at three dimensional compact toroid compression by a liner the maximum plasma pressure growth rate, plasma and magnetic energy strongly depend on the mode of the shell motion and on toroid plasma distribution in initial state, the quasispherical liner toroid compression being the most favourable one. Under this mode thermal plasma energy relation to magnetic field energy is improved. There is a tendency to reduction with the part of plasma volume compression in which the convective stability criterion is broken
