Fabrication of ICF Reactor Targets Based on Symmetrization of Solid Fuel.

摘要

Tritium self-heats at a rate of 0.97 W/mole because of its beta activity. This energy drives preferential sublimation of solid T sub 2 or DT from regions where a layer is thicker and warmer to regions where the layer is thinner and colder. A frozen tritium layer inside an isothermal container approaches isotropy exponentially with a time constant as short as 14.4 minutes. Targets Isotropized by Radioactively Induced Sublimation (IRIS) and sized for an ICF reactor demonstrate high gain and offer real fabrication advantages. 9 refs., 2 figs. (ERA citation 13:058254)
