Abstract

The method of current shunting in the experiments on Z-pinch compression has been developed. Electrical transients with current shunting have been analyzed, and the requirements to the shunting elements and the primary-discharge electrical circuits are considered. The design of the discharge chamber with the additional shunting electrodes of the electrodynamic installation is presented. In this chamber, two shunting modes are possible. These are the self-breakdown mode and the mode with the shunting-gaps ignition. The first experimental results of current shunting with steel samples are presented.
