TLDR
The Tokamak Fusion Test Reactor (TFTR) is a large tokamak which has performed experiments with 50:50 deuterium - tritium fuelled plasmas as discussed by the authors.Abstract:
The Tokamak Fusion Test Reactor (TFTR) is a large tokamak which has performed experiments with 50:50 deuterium - tritium fuelled plasmas. Since 1993, TFTR has produced about 1090 D - T plasmas using about 100 grams of tritium and producing about 1.6 GJ of D - T fusion energy. These plasmas have significant populations of 3.5 MeV alphas (the charged D - T fusion product). TFTR research has focused on alpha particle confinement, alpha driven modes, and alpha heating studies. Maximum D - T fusion power production has aided these studies, requiring simultaneously operation at high input heating power and large energy confinement time (to produce the highest temperature and density), while maintaining low impurity content. The principal limitation to the TFTR fusion power production was the disruptive stability limit. Secondary limitations were the confinement time, and limiter power handling capability.read more

TL;DR: The results from the alpha particle diagnostics agreed with the classical single particle confinement model in MHD quiescent discharges as mentioned in this paper, and the alpha loss due to toroidal field ripple was identified in some cases, and low radial diffusivity inferred for high energy alphas was consistent with orbit averaging over small scale turbulence.

The behaviour of fast ions in tokamak experiments
W.W. Heidbrink,G.J. Sadler +1 more
TL;DR: In this paper, the velocity distribution of fast ion populations is determined primarily by Coulomb scattering; during wave heating, perpendicular acceleration by the RF waves is also important, and this velocity distribution is typically much slower than thermal transport, except during MHD events.
