Research Abstract

Behavior of ablated metal vapor after a fusion burn in a laser fusion reactor with a liquid wall was studied experimentally and numerically. In the experiment, thin Pb membrane was heated with electric discharge and evaporated metal was corrected on a witness plate. The diameter of aerosols was about 30nm which agreed with numerical results. The numerical simulation showed that a 60cm-diameter-core was formed 6ms after the fusion burn at the stagnation point due to collision with counter plume from the other side of the chamber. The number density of aerosols in the core was about 10^<11>n/cm^3. Aerosols also collide with those from the other side and stagnate in the core.
