Abstract

High-density plasmas with peak-to-average values greater than two have been produced by pellet injection in TFTR. In ohmically heated plasmas at 1.6 MA, ntau values of 1.4 x 10¹⁴ cm^-3. s have been achieved. Tangential neutral beam injection in these plasmas is characterized by power deposition profiles peaked near the q = 2 surface, values of global confinement that do not deteriorate relative to those obtained in gas-fueled cases with more centrally peaked power deposition profiles, and a strong transient reheat of the central plasma during which the central energy confinement time exceeds 1 s.
