Liner implosion experiments with a pipe foam target on pulsed power transformer

Liner implosions using a newly designed pulsed power transformer have been studied. The transformer generates a 1 MA current pulse with a 250-ns rise time. The mass and initial radius of the liner has been optimized. An aluminum L -shell radiation with a peak power of 20 GW in a 40-ns pulse width wa...

Description
Summary:Liner implosions using a newly designed pulsed power transformer have been studied. The transformer generates a 1 MA current pulse with a 250-ns rise time. The mass and initial radius of the liner has been optimized. An aluminum L -shell radiation with a peak power of 20 GW in a 40-ns pulse width was measured. This radiation can be used as the pump radiation of an Al/F X-ray laser scheme. In experiments with pipe-foam targets at the axis of cylindrical symmetry, the linearity of the aluminum plasma implosion was improved. The radiation from the inside of the target was observed by a time-integrated X-ray pinhole camera.
