Preliminary studies have been performed to evaluate the production of aerosols in wetted wall and solid wall IFE chamber configurations. Molten lead and flibe were examined for a wetted-wall chamber 6.5 m in radius, giving aerosol mass concentrations of 20 mg/m3 and 10 mg/m3, respectively, for a simulated 458 MJ indirect-drive target microexplosion. Solid wall materials of tungsten and steel exposed to a 154 MJ direct-drive target microexplosion within an equivalent chamber produced mass concentrations of 0.4 mg/m3 and 90 mg/m3, respectively.
