Properties of Z-pinches Driven by Short and Long Risetime Currents on Double EAGLE and Saturn.
Abstract
Designing a Z-pinch driver to operate with a longer current risetime can result in significant cost and space savings, and reduced power flow risk due to the smaller voltage and power required. However, the resulting longer implosion time exposes the pinch to greater risk of disruption by Rayleigh-Taylor instability growth or by any initial asymmetries present in the load. In this work we present a comparative analysis of K-shell radiation data from Z-pinches which have been driven by both short (<= 100 ns) and long (>= 200 ns) implosions on Double EAGLE (3-4 MA) and Saturn (6-7 MA). Results presented are primarily from argon gas puff implosions.
