Dynamic Stabilization of the Rayleigh-Taylor Instability on Laser-Imploded Shells.

Abstract

By continually modulating the intensity of the driving laser beams, the fastest-growing modes of Rayleigh-Taylor instability on the surface of an imploding laser fusion pellet can be dynamically stabilized. Both theory and numerical simulation are presented to support this conclusion. The band of modes stabilized extends to sufficiently long wavelength that rather high aspect ratio shells apparently can be imploded successfully. Similar beam modulation or bunching techniques should work for electron, ion and heavy ion pellet implosion schemes. (Author)
