Redi, S.H. Batha, M.G. Bell, R.V. Budny, D.S. Darrow, F.M. Levinton, D.C. McCune, S.S. Medley, M.P. Petrov, S. von Goeler, R.B. White, M.C. Zarnstorff, S.J. Zweben, and the TFTR Team Neoclassical simulations of alpha particle density profiles in high fusion power plasmas on the Tokamak Fusion Test Reactor (TFTR) [Phys. Plasmas 5 (1998) 1577] are found to be in good agreement with measurements of the alpha distribution function made with a sensitive active neutral particle diagnostic. The calculations are carried out in Hamiltonian magnetic coordinates with a fast, particle-following Monte Carlo code which includes the neoclassical transport processes, a recent first-principles model for stochastic ripple loss and collisional effects. New global loss and confinement domain calculations allow an estimate of the actual alpha particle densities measured with the pellet charge exchange diagnostic.
