PLT neutral beam heating results

Technical Report ·
DOI:https://doi.org/10.2172/6504076· OSTI ID:6504076
Experimental results from high-power neutral beam injection experiments on the PLT (Princeton Large Torus) tokamak are reported. At the highest beam powers (2.1 MW) and lowest plasma densities (n/sub e/(O) = 4.5 x 10/sup -13/ cm/sup -3/), ion temperatures of 5.5 keV are achieved. The ion collisionality ..nu..*/sub i/ drops below 0.1 over much of the radial profile. Electron heating of ..delta..T/sub e//T/sub e/ approx. = 50% 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.
