The large Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory has entered a new regime of “enhanced confinement” operation. The first spectacular consequence of this new regime is the attainment of a record ion temperature of 20 keV—more than 200 million kelvin. For the first time, a tokamak is creating plasmas with ion temperatures hot enough for ignition and fusion‐reactor operation.
