Description

A load structure with tailored density profile which delays the onset of the Rayleigh-Taylor instability development in imploding Z pinches by inverting acceleration of the magnetic field/plasma interface is proposed and studied numerically. This approach makes it possible to start gas-puff implosions from large radii (say, 8cm) and produce significant K-shell yield with current pulse duration of 250ns and longer. It could also be used to mitigate imprinting of initial perturbations into laser fusion targets. copyright 1996 The American Physical Society
