On stabilization of gas puff implosion: experiment and simulation

Abstract

A double gas puff was used to study the mitigation of the magneto-Rayleigh-Taylor (RT) instabilities for long implosion times (up to 250 ns). The experiments have been performed on the inductive storage GIT-4 (1.7 MA, 120 ns) generator. Current division between the outer and inner shells was controlled using magnetron-discharge preionization. The implosion of the a double gas puff, with the improved preionization, results in the formation of a uniform plasma column. The results of two-dimensional (2-D) radiation-magnetohydrodynamic simulations support the experimental results: a double gas puff implosion mitigates the RT instabilities, leading to the development of only small-amplitude waves. The 2-D simulation allowed us to explain the halo effect seen in the experiments: the use of the low hybrid conductivity in the calculation demonstrated the existence of the high density plasma core surrounded by a low density plasma halo.
