Effects of radiofrequency-induced radial diffusion on triton burnupFunded under: FP3-FUSION 11C
Effects of radiofrequency (rf)-induced radial diffusion on triton burnup are studied for D(3He) plasmas with 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 highly localised in the plasma centre, tritons are driven out from the centre because of rf-induced diffusion in the second harmonic resonance. The emission profile of the 14 MeV neutrons due to 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.
