Topic description

High-temperature superconducting (HTS) magnets represent a major breakthrough for nuclear fusion, enabling the development of compact, economically viable reactors with high power density. However, their design still facessignificantphysical and technological challenges, making advanced numerical modeling essential for progress. As for ITER, one of the key challenges remains power exhaust, as steady-state heat fluxes could exceed the technological limits of plasma-facing components (PFCs). Various strategies allow tokamaks to operate in dissipative regimes, such as impurity injection (Neon, Argon), which dissipates energy at the edge but dilutes the plasma. Among these, the detached plasma regime is particularly promising, as it dramatically reduces plasma temperature at the wall, leading to recombination into a protective n...
