Optimization of plasma focusing device by electrode geometry and dielectric insulator

Summary form only given, as follows. For a pulsed neutron generation, a low energy Mather-type plasma focus device has been designed and experimented. The stored energy and discharge peak current are 2.2 kJ (capacitor bank; /spl mu/F /spl times/ 8) 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 /spl mu/F /spl rarr/ 32 /spl mu/F) has been obtained, and focusing condition will be explained.
