Abstract
Effects of radio‐frequency (RF)‐induced radial diffusion on triton burnup are studied for D(3He) plasmas with an ion cyclotron range of frequencies heating in the fundamental minority regime. The triton distribution is determined from a Fokker–Planck equation including a radial diffusion term. Provided that the RF power is extremely localized in the plasma center, tritons are driven out from the center because of RF‐induced diffusion in the second harmonic resonance and the emission profile of the 14 MeV neutrons due to deuterium tritium (D–T) reactions can possibly be flattened appreciably. This may lead to verification of RF‐induced radial diffusion of the ions only through neutron detection.Keywords
