摘要: The plasma-material interface and its impact on the performance of magnetically confined thermonuclear fusion plasmas are considered to be one key scientific gaps in realization nuclear power. At this interface, high particle heat flux from plasma can limit material’s lifetime reliability therefore hinder operation device. Lithium-based surfaces now being used major magnetic confinement devices have observed profound effects including enhanced confinement, suppression control edge localized modes (ELM), lower hydrogen recycling impurity suppression. critical spatial scale length deuterium helium interactions lithium ranges between 5–100 nm depending incident energies at configuration. also range liquid state solid coatings a variety substrates (e.g., graphite, stainless steel, refractory me...
