Linear experiment on verification of Rayleigh-Taylor instability magnetic stabilization effect (joint LANL/VNIIEF experiment Pegasus-2)

摘要

Summary form only given, as follows. The Pegasus-2 liner implosion experiment (RUS 5) has been conducted, in which perturbation growths for two perturbation types were compared. On one half (over height) of a cylindrical liner azimuthally symmetric perturbations were made. On the other half of the liner the perturbations were of the same wavelength and amplitude, but the angle between the wave vector and the cylinder axis was 45 degrees (helical perturbations). The experimental radiographs show that there is essentially no helical perturbation growth, while the azimuthally symmetric perturbations grow by many times. This result agrees with the theoretical prediction.
