Current instability of `Snow Plough`

Abstract

The analysis of data obtained in experiments on liner implosion at the large thermonuclear installations as Module-A5, Saturn, and Angara-5 show substantial discrepancy with the supposed Rayleigh-Taylor scenario of the liner shell disruption. Apparently there must be an alternative scenario which gives rise to the fall-through of the current into the internal regions of the liner, determining thus future behaviour of mass. Moreover, exact correlation between the process of stratification and occurrence of the lighting kernel in the region near the axis have been observed in the Modul-5 installation. A new two-fluid theoretical MHD model is described in the paper, which can well explain all the phases of the liner evolution observed in real experiments. (J.U.). 1 fig., 3 refs.
