Neutrons characteristic of nuclear fusion have been produced sustainably inside a device that is small enough to fit on a tabletop. Yue Zhang at the University of Washington and colleagues observed the neutrons following efforts to stabilize the accelerated plasma contained within a Z-pinch, a device that for decades has been used by astronomers to recreate the hot plasmas typical of a stellar interior. The new work offers a potential route towards compact fusion-energy generators, as an alternative to large-scale, tokamak-based devices.
A Z-pinch device works by running a strong current along a tube of accelerated plasma, inducing a Lorentz force that generates a strong magnetic field within the plasma. This field “pinches” the plasma by bringing particles closer together – increasing its pressure, and therefore, its temperature.
