Plasma and Fusion

Plasma and Fusion

Fusion occurs in Plasma - Ions and Electrons. Plasma is formed when a gas is energized, causing its atoms to lose electrons and become ionized. This can happen through intense heating, electrical discharges, or energy released from chemical reactions. The resulting plasma, a mix of free electrons and ions, conducts electricity and responds to magnetic fields

Magnetic Confinement

Magnetic Confinement

Magnetic devices are humanity's best bet to confine plasma effectively, for fusion. Charged particles in plasma, such as ions and electrons, move in helical patterns, following magnetic field lines. To confine them indefinitely, the magnetic field lines must form a continuous loop.  The simplest design to achieve this is a torus—a donut-shaped configuration where magnetic field lines form closed loops.

A Brand New Design Paradigm 

A Brand New Design Paradigm 

While a torus provides confinement, it introduces drift and instabilities in the plasma, which stop the fusion reaction. To counteract these issues, engineers introduced twists in the magnetic fields. Meanwhile, new research in Stellarator design (inspired by the figure-eight shape) is shown to inherently stabilize the plasma without relying on external currents. Pathbreaking scientific advancements in HTS magnet technology, high-performance computing, and material science have opened up a new paradigm in designing fusion reactors. It is now becoming possible to explore complex magnetic field geometries resembling Möbius strips and Klein bottles, where the field lines close in on themselves without defining a distinct inner or outer surface.
