China’s flagship fusion experiment has crossed a line that many physicists once treated as a hard stop, pushing plasma density beyond a limit that had constrained reactors for decades. By finding a ...

Dubbed 'EAST,' China's 'artificial Sun' mimics the physics of Sun and stars to generate energy from hydrogen electrons.

China's artificial sun breaks density limit that caused fusion experiments to fail, moving closer to clean energy.

With impurity levels better controlled, the plasma was able to move into what researchers describe as a stable “density free zone,” operating beyond the traditional limit without triggering ...
