Optimization of Plasma Focusing Device by Electrode Geometry and Dielectric Insulator

Abstract

For a pulsed neutron generation, a low energy Mather-type plasma focus device has been designed and experimented in Hanyang University. The stored energy and discharge peak current are 2.2 kJ (capacitor bank; ) and 147 kA respectively. To optimize in this plasma focus device, different geometry (shape and length), dielectric insulator and capacitance of the capacitor have been tried. A new plasma focusing with increased capacitance ( 8 uF → 32 uF) has been obtained focusing condition will be explained.
