Abstract

Assuming a deuterium-tritium (DT) burning plasma, effect of the nuclear plus interference (NI) scattering is newly incorporated into the alpha-particle orbit simulation. The effect of the NI scattering on the energetic alpha-particles orbit and confinement in a magnetic fusion device is examined. It is shown that due to transition of the alpha-particle orbit by NI scattering, the fraction of the alpha-particles lost from the plasma during their slowing-down process to the initial generation decreases to a certain extent.
