Abstract

Z-pinches with preembedded magnetic field (Bz0) undergo radial implosion due to the J × B force while compressing the plasma and the embedded magnetic flux. In this work, we demonstrate for the first time a self-generated plasma rotation for a cylindrical Z-pinch implosion with Bz0 [1]. The rotation direction is found to depend on the direction of Bz0. The observed rotation velocity is found to be comparable to the implosion velocity. The rotation is found to affect the implosion dynamics by exerting a centrifugal force and by mitigating plasma instabilities. The evolution of the rotation is seen to be consistent with magnetic flux surface isorotation, a novel observation in a Z pinch, which is a prototypical time-dependent system.
