Popis: On the S-300 pulsed power machine at the Kurchatov Institute, some experimental activity is devoted to the prospects of Inertial Fusion Energy (IFE) program [1]. The results of experiments devoted to the study of operation of magnetically insulated transporting line (MITL), by the linear current flow density on the inner electrode surface up to j ≈ 7 MA/cm on S-300 are presented. The specific parameters of this current-carrying line correspond to those of the conceptual project of IFE reactor based on the fast Z-pinch. The duration of efficient functioning for such a line has been measured and possible reasons for broken isolation have been studied. Instability of expanding plasma sheath inside this line were recorded, probably it was of MHD origin. The processes of electrode explosion and subsequent dynamics of the dense plasma turn out to be in a good agreement with results of 1-D numerical modeling based on the NPINCH code, by taking into account equilibrium of state for both metal and plasma. A series of SXR and HXR measurements have been carried out clarifying the dynamics and parameters of rare plasmas inside the MITL gap.
