| Research Abstract |
High-density and high-performance plasma, which was identified in the Large Helical Device, has been extrapolated to self-burning plasmas by assuming a dimensional physical similarity. And the feasibility of an innovative scientific model, which enables access to the self-burning regime with relatively high-density and low-temperature conditions compared to the conventional burning scenario in the thermo-nuclear fusion, has been corroborated. While the direct fueling to the core plasma is inevitable for the realization of the proposed scenario, it allows to mitigate engineering demands such as extreme high heat flux onto the plasma facing materials by reducing the plasma temperature and the minimum fusion output to sustain self-burning plasma.
