The implosion dynamics of a high density -pinch plasma driven by a spinning annular gas-puff of negligible thickness is investigated. Numerical results show that spinning the outer Z-pinch plasma alone, though adequate to suppress the growth of RT instability, is not enough to achieve thermonuclear fusion conditions with staged pinch. However if, together with the spinning gas-puff, one uses high- Z impurity seeded DT-fibre, then owing to radiative collapse, thermonuclear fusion conditions are achievable.
