Analysis of physical processes in ICF target chambers
When a high-gain inertial fusion target explodes, roughly one third of the energy is released in the form of x-rays and energetic ions, which can damage the wall of the chamber. One method of protecting the wall is to place a gas in the chamber cavity. The authors use a 1-D Lagrangian radiation-hydrodynamics code (CONRAD) to study the target energy deposition in this cavity gas and first surface material, the growth of and radiative emission from the microfireball, the expansion of the shock front, the vaporization and hydromotion of the first surface material, and the recondensation of that material back onto the wall. The authors describe recent improvements to CONRAD, and present results for two target chamber designs currently being considered by Lawrence Livermore National Laboratory for the Laboratory Microfusion Facility.
