Study of plasma parameters in a spinning thick-gas-puff staged pinch

The dynamics of a finite-thickness imploding spinning gas-puff is studied f or a staged pinch device. Our numerical results demonstrate that although l arge spin velocities help to suppress R-T instability, but they adversely a ffect the fusion parameters. However, with a normalized puff thickness of L -p = 0.01 and spin velocities between Omega = (1.0 - 2.0) x 10(-3)ns(-1), o ne may achieve a stable pinch plasma close to thermonuclear fusion conditio ns. We also studied the effect of opacity on the temperature of the fiber a t the final stage. Our findings would be relevant in gas-liner and staged p inch experiments for realizing fusion conditions.
