India's Private Fusion Tokamak PRAGYA Achieves Plasma Operation
Bengaluru-based deep-tech energy startup Pranos Fusion has produced plasma in its experimental device PRAGYA. The company states that PRAGYA is India's first compact tokamak developed by a private enterprise, marking a transition in India's private fusion research and development from the design and manufacturing phase to experimental operation. PRAGYA adopts a compact, low-aspect-ratio tokamak design, primarily used to generate, confine, and control plasma. Tokamaks use strong magnetic fields to confine high-temperature plasma within a toroidal vacuum vessel, creating conditions for future fusion of light atomic nuclei. The fundamental process of fusion reactions is the same mechanism by which the Sun releases energy, but engineering implementation still faces multiple challenges in plasma confinement, magnets, materials, and control systems.
