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.

U.S. Research Reveals Diamond Melting Mechanism at High Pressure, Potentially Enhancing Inertial Confinement Fusion Performance

A research team at Lawrence Livermore National Laboratory (LLNL) in the U.S. recently published a study in Nature Physics reporting that the latest dynamic compression experiments have, for the first time, directly recorded atomic structural changes during diamond melting under extreme high pressure. The experiments showed that under high-pressure conditions, solid diamond can float in liquid metallic carbon, similar to ice floating on water. Diamond is not only a high-hardness carbon material but is also used as the fuel target capsule shell in inertial confinement fusion experiments. When intense lasers drive the capsule implosion, the compression and melting behavior of the diamond shell can affect whether the fusion fuel reaches the required high-temperature, high-pressure state. Meanwhile, the planetary science community has long focused on the high-pressure behavior of carbon in the deep interiors of ice giant planets...

US Study Shows Inertial Fusion Implosions Can Tolerate Certain Asymmetries

Researchers at the Lawrence Livermore National Laboratory (LLNL) in the US have recently found that implosion designs for inertial fusion energy (IFE) can withstand considerable imperfections before performance degrades sharply. This result aids in the design of fuel targets for future fusion power plants, particularly in assessing the tolerance of target capsules to errors under high-frequency injection and laser-driven conditions. The study's simulation results show the density (top) and temperature (bottom) at the instant just before fusion reactions peak in an asymmetric implosion. The hottest spot coincides with the point of highest fuel density, indicating direct ignition of high-density fuel jets driven by asymmetry. The image was recently selected for the cover of Physics of Plasmas...
