Description

The alpha-particle emission spectrum in beam-injected (non-Maxwellian) deuterium-tritium (DT) burning plasma is examined by solving the Boltzmann-Fokker-Planck (BFP) equations for deuteron, triton and alpha-particle simultaneously. It is shown that owing to the existence of energetic component in fuel-ion energy distribution functions due to neutral-beam injection (NBI) and/or nuclear elastic scattering (NES), the generation rate of the high-energy (>3.52 MeV) alpha-particle increases significantly compared with the case for Gaussian distribution. The influence of the broadened energy spectrum on the alpha-heating characteristics is discussed. (author)
