On perspectives of D-T plasma ignition at quasi-adiabatic compression in Z-/spl Theta/ pinch geometry

Abstract

The stability of adiabatic compression of previously heated magnetized plasma by a longitudinal magnetic field is investigated at different ways of its amplification. Is shown, that tenfold radial compression is possible in Z-/spl Theta/ pinch geometry. In frameworks of 1.5-D equations in MGD approximation the perspectives of D-T plasma ignition are analyzed at quasi-adiabatic compression by a longitudinal magnetic field of Z-/spl Theta/ pinch. As criterion of ignition the duple value of a system equal 0.31+1 was considered.
