Experimental results from high-power neutral-beam-injection experiments on the Princeton Large Torus tokamak are reported. At the highest beam powers (2.4 MW) and lowest plasma densities [ne(0)=5×1013 cm-3], ion temperatures of 6.5 keV are achieved. The ion collisionality νi* drops below 0.1 over much of the radial profile. Electron heating of ΔTeTe50% has also been observed, consistent with the gross energy-confinement time of the Ohmically heated plasma, but indicative of enhanced electron-energy confinement in the core of the plasma.
