China's EAST reactor achieved plasma densities 1.65x beyond theoretical limits, solving fusion's 70-year puzzle and bringing ...

Here’s what you’ll learn when you read this story: The plasma density barrier is a mathematical limit to the density of plasma that can exist in a tokamak before destabilizing. A new study led by a ...

NIIEFA has tested a high-temperature superconductor wire (HTSC) for the TRT tokamak, achieving record current and magnetic field parameters.

Engineers at the UK’s STEP (Spherical Tokamak for Energy Production) program have successfully tested ...

For decades, nuclear fusion has been described as the holy grail of clean power, a way to generate vast amounts of energy by ...

Getting a significant energy return from tokamak-based nuclear fusion reactors depends for a large part on plasma density, but increasing said density is tricky, as beyond a certain point the plasma ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside the sun. But to recreate the process on Earth, we must control ...

Experiments show fusion plasma can stay stable at higher densities by controlling reactor walls, challenging long-standing limits.
