Evaluation of High Energy Density Plasma in Counter‐Facing Plasma Focus Device Driven by Laser‐Triggered Pulse Power System

Abstract

SUMMARY A laser‐trigger system has been introduced to a pulse power system composed of counter‐facing plasma focus electrodes in order to make high energy density plasma. Lithium plasmas made by a YAG laser ablation were used for both triggering the plasma focus and supplying the source of the high energy density plasma. Also the supply system of plasma source has been improved for stability and repeatability of the device. Operational principle of the device, details of the configuration, and basic characteristics of the triggering system are shown together with possible applications of the device.
