Progress in the Light Ion Driven Inertial Confinement Fusion Program

摘要

The goal of the light ion inertial confinement fusion (ICF) program is high fusion yield for defense and energy applications. The first lithium-driven hohlraum experiments at 1400 TW/g are reported. The lithium beam intensity is presently limited to 1.4 (+-) 0.4 TW/cm(sup 2) (averaged over a 6 mm diameter sphere) due to a combination of beam divergence and limited lithium beam power. Surface contamination in the diode plays an important role in limiting the lithium power. Concepts have been developed for beam transport over several meters. Synergism exists between light- and heavy-ion ICF in areas such as transport and target physics.
