Princeton scientists overcome key setback in achieving nuclear fusion

The researchers are one step closer to making the technology viable.

Physicists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have taken a critical step forward toward achieving nuclear fusion.

The scientists traced back the collapse to the 3D disordering of strong magnetic fields.


Magnetic fields are used in fusion facilities as substitutes for the powerful gravity that holds fusion reactions in place in celestial bodies. However, in laboratory experiments these fields are disordered by plasma instability resulting in a superhot plasma rapidly escaping confinement. The ensuing heat can damage fusion facility walls.
