Nuclear physics startups are deploying high-temperature superconducting (HTS) magnets to achieve higher magnetic field strengths in compact tokamak designs. The approach reduces the overall physical footprint required for plasma confinement.
Magnet Density
Recent field tests demonstrate HTS tape carrying double the current density of conventional low-temperature alternatives. This breakthrough allows for smaller, less capital-intensive reactor geometry.
Thermal Exhaust Management
Sustaining burning plasma presents severe thermal challenges to reactor walls. Research teams are developing advanced liquid-metal divertors to handle power densities exceeding space-shuttle reentry conditions.
