摘要：
This paper presents the analysis of experiments carried out on the GIT-4 and GIT-12 installations with microsecond megaampere plasma opening switches. Switches with axial and radial plasma injection are considered. It is shown that the conduction current, depending on the switch geometry and plasma density, is given by the magnetohydrodynamic scaling. The experimentally observed switch features in the opening stage can be explained in frame of the modified erosion model of switch opening.
