Abstract

Distortion in the fuel-ion (deuteron and triton) velocity distribution functions due to nuclear elastic scattering (NES) by beam ion and a-particle during neutral-beam-injection (NBI) plasma heating operation is studied by simultaneously solving the Boltzmann-Fokker-Planck (BFP) equations for deuteron, triton, α-particle and beam ion in the deuterium-tritium (DT) thermonuclear plasmas. Using the obtained distribution functions, enhancement in the T(d,n)4He fusion reaction rate coefficient between background deuteron and triton are estimated. It is shown that the enhancement in the T(d,n)4He reaction rate coefficient becomes appreciable in low-density operations, i.e. ne ≤ 5×1019m -3.
