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 ...

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 ...

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

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 ...

An experiment at the Princeton Plasma Physics Laboratory produced a 1-million-ampere plasma current with a new reactor last month, setting a world record for that type of reactor and opening the door ...

Tokamak plasma systems hold great promise in realising practical nuclear fusion, yet their full potential is constrained by the risk of disruptions – sudden, often catastrophic, losses of plasma ...
