Recent progress on the Tokamak Fusion Test Reactor
TLDR
The deuterium-tritium (D-T) experiments on the Tokamak Fusion Test Reactor (TFTR) have yielded unique information on the confinement, heating and alpha particle physics of reactor scale D-T plasmas as well as the first experience with tritium handling and D-Ts neutron activation in an experimental environment as discussed by the authors.Abstract:
The deuterium-tritium (D-T) experiments on the Tokamak Fusion Test Reactor (TFTR) have yielded unique information on the confinement, heating and alpha particle physics of reactor scale D-T plasmas as well as the first experience with tritium handling and D-T neutron activation in an experimental environment. The D-T plasmas produced and studied in TFTR have peak fusion power of 10.7 MW with central fusion power densities of 2.8 MWm−3 which is similar to the 1.7 MWm−3 fusion power densities projected for 1,500 MW operation of the International Thermonuclear Experimental Reactor (ITER). Detailed alpha particle measurements have confirmed alpha confinement and heating of the D-T plasma by alpha particles as expected. Reversed shear, highli and internal barrier advanced tokamak operating modes have been produced in TFTR which have the potential to double the fusion power to ∼20 MW which would also allow the study of alpha particle effects under conditions very similar to those projected for ITER. TFTR is also investigating two new innovations, alpha channeling and controlled transport barriers, which have the potential to significantly improve the standard advanced tokamak.read more

TL;DR: In this paper, a new tokamak confinement regime has been observed on the Tokamak Fusion Test Reactor (TFTR), where particle and ion thermal diffusivities drop precipitously by a factor of \ensuremath{\sim}40 to the neoclassical level for the particles and to much less than the NE value for the ions in the region with reversed shear.

TL;DR: Values of normalized beta, up to 4 ({percent}-{ital m}-T/MA), energy confinement are a factor of 3 better than {ital L} mode, and at least 50% of the noninductive plasma current in this regime demonstrates compatibility with requirements for a steady-state high-beta tokamak power plant.

TL;DR: Lower hybrid waves are a demonstrated, continuous means of driving toroidal current in a tokamak, and waves traveling in one poloidal direction, in addition to being directed in one toroidal direction are shown to be the most efficient drivers of current in the presence of the energetic {alpha}-particles.
