Fast Equilibrating 1st Wall -Majeski

The invention is primarily a composition of matter, which combines two pre-existing materials to produce new utility. Specifically, a “fast equilibrating” wall would consist of a 100-200 micron layer of plasma-facing material, backed with a hydrogen diffusion barrier. A candidate hydrogen barrier is a thin layer of densified ceramic. Densified ceramics have been shown to function as effective hydrogen diffusion barriers. By use of this construction, the plasma facing material can approach a saturated equilibrium two orders of magnitude more rapidly than is possible with conventional constructions for plasma facing materials
