Computer simulation of recent laser driven implosions of glass microshells

Conference ·
OSTI ID:7299902
Recent experiments at the LLL 2.0 terawatt laser irradiation facility Argus have been conducted on glass microshells filled with equimolar DT gas. A variety of microshell dimensions and laser pulse widths have been used with the best results producing in excess of 10/sup 8/ fusion reactions. Numerical simulation of selected experiments using the LASNEX computer code confirm the measured performance. Peak DT ion temperatures of about 5 keV and densities of .2 gm/cm/sup 3/ are calculated and are in agreement with that from neutron time-of-flight and alpha particle spectral measurements together with x-ray diagnostics. Laser light absorption is about 20% efficient. General characteristics of ''exploding pusher'' targets will be discussed.
