Abstract

The TFTR tokamak has reached its original machine design specifications (I_p=2.5 MA and B_T=5.2 T). Recently, the D degrees neutral beam heating power has been increased to 6.3 MW. By operating at low plasma current (I_p approximately=0.8 MA) and low density (n_e approximately=1*10¹⁹ m^-3), high ion temperatures (9+or-2 keV) and rotation speeds (7*10⁵ m/s) have been achieved during injection. At the opposite extreme, pellet injection into high current plasmas has been used to increase the line-average density to 8*10 ¹⁹ m^-3 and the central density to 1.6*10 ²⁰ m^-3. This wide range of operating conditions has enabled the authors to conduct scaling studies of the global energy confinement time in both ohmically and beam heated discharges as well as more detailed transport studies of the profile dependence.
