  Deuterium–tritium fusionKeystone

  Connects 16 concepts

  Deuterium–tritium fusion is a type of nuclear fusion in which one deuterium (2H) nucleus (deuteron) fuses with one tritium (3H) nucleus (triton), giving one helium-4 nucleus, one free neutron, and 17.6 MeV of total energy coming from both the neutron and helium.

  Heat flux

  In physics and engineering, heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat-flow rate intensity, is a flow of energy per unit area per unit time.

  Sputtering

  In physics, sputtering is a phenomenon in which microscopic particles of a solid material are ejected from its surface, after the material is itself bombarded by energetic particles of a plasma or gas.

  Plasma-facing material

  In nuclear fusion power research, the plasma-facing material is any material used to construct the plasma-facing components (PFC) those components exposed to the plasma within which nuclear fusion occurs, and particularly the material used for the lining the first wall or divertor region of the reactor vessel.

  Divertor

  In magnetic confinement fusion, a divertor is a device which extracts heat and ash from fusion plasmas by averting direct contact between the confined plasma and the main chamber wall.
