Abstract
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 pr oposed and studied numerically. This approach makes it possible to sta rt gas-puff-implosions from large radii (say, 8 cm) and produce signif icant K-shell yield with current pulse duration of 250 ns and longer. It could also be used to mitigate imprinting of initial perturbations into laser fusion targets.
