Progress in lithium beam focusing and beam-target interaction experiments at Sandia National Laboratories
Significant progress in the generation and focusing of ion beams generated by PBFA II has enabled us to begin experiments in ion beam coupling and target physics. Data from these experiments indicates that we can reproducibly deliver {approximately}50 KJ of 5 MeV protons at an average power intensity of 3.5 TW/cm{sup 2} to a 6 mm diameter by 6 mm tall cylindrical target. The implosion of the spherical exploding pusher targets and the radiation production from foam-filled cylindrical thermal targets were studied in these experiments. They demonstrated that high quality target data can be obtained on PBFA II. Specific deposition rates of about 100 TW/g were achieved in these experiments. This deposition rate marks the boundary between the regime where enhanced ion deposition and equation-of-state (EOS) physics are studied (10--100 TW/g) and the regime where radiation-conversion and radiation-transport physics are studied (100--1000 TW/g). Experiments in the radiation-conversion regime are now of primary importance in our program because these experiments will test the target physics basis for ion-driven ICF.
