Effect of current rise time on electromagnetic driven solid liner implosion

The electromagnetic driven solid liner implosion is one of the high energy density (HEDP) experimental techniques. Some drivers have been constructed in the past years, these drivers are varied in peak current and current rise time. This paper analyzes the effect of current rise time on the solid liner implosion, in order to provide some advice on the choice of the existed drivers which will be appropriate for solid liner implosion experiment. Calculations were performed under uncompressible zero dimension model, the effects of liner size, current amplitude and current rise time on implosion velocity were obtained. The results indicate that drivers with current rise time above 2 microsecond would be appropriate for solid liner implosion experiment. The analysis also lays the theoretical foundation for the future design of high capacity drivers used for solid liner implosion experiment.
