Experiments with polymer coated microspheres irradiated by the Shiva laser system

PDF Version Also Available for Download.

Description

Polymer coated spherical targets have been irradiated by the Shiva laser system in an effort to compress the contained 10 mg/cc DT fuel to super liquid densities. Glass microspheres of 140 ..mu..m ID and 5 ..mu..m wall thickness with polymer coatings 15 ..mu..m to 100 ..mu..m thick have been irradiated with laser pulses of 4 kilojoules in 200 psec FWHM. Target performance was diagnosed with neutron yield measurements, radiochemistry, Argon line imaging, and x-ray imaging techniques. Ball in plate targets achieved greater implosion symmetry than free-standing ball targets. With yields of 10/sup 7/ to 10/sup 8/ neutrons, targets reached DT … continued below

Ball in plate targets achieved greater implosion symmetry than free-standing ball targets. With yields of 10/sup 7/ to 10/sup 8/ neutrons, targets reached DT fuel compressions of several times liquid density.
