Evidence of stabilization in the Z-pinch.
TL;DR: Experimental results show a stable period which is over 700 times the expected instability growth time in a static Z-pinch, and the experimentally measured axial velocity shear is greater than the theoretical threshold during the stable period and approximately zero afterwards when the magnetic mode fluctuations are high.
