Spherical tokamaks, characterized by their small aspect ratio (ratio of major to minor radius), offer significant advantages in fusion reactor design. Unlike conventional tokamaks, where the plasma is shaped more like a doughnut, spherical tokamaks resemble a cored apple, allowing for stronger magnetic curvature and improved stability. This geometry leads to higher plasma pressure for a given magnetic field strength, making them more efficient in terms of confinement. Additionally, their compact size reduces construction costs and enables the use of high-temperature superconducting (HTS) magnets, further enhancing performance. The small aspect ratio also facilitates better access to the plasma core, crucial for heating and fueling strategies. Emerging research suggests that these devices can be optimized to sustain high-beta plasmas, making them potential candidates for next-generation fusion reactors, especially in applications where space and scalability are critical, such as compact power plants and mobile energy solutions.
