Abstract :
The Rayleigh-Taylor instability is well known to be the main impediment to the efficient implosion of gas puffs with a large initial radius. This has been demonstrated in a number of experiments. The R-T instability could be mitigated by the so-called snowplow mechanism responsible for enhanced efficiency of multilayer gas puff Z-pinch loads. The snowplow mechanism employs the stability of the shock wave driven into the load by magnetic pressure. The snowplow stability mechanism is used both in multilayer gas puffs and in structured loads such as large-diameter uniform fill loads and Z-pinch loads with tailored density profiles
