Triton burnup profile measurements

The TFTR helium proportional counters measured the 14 MeV neutron emission profiles from the 1 MeV tritons produced by d(d,p)t fusion reactions in deuterium plasmas. The magnitude and profile of the 1 MeV triton burnup indicate that there is no energetic triton transport (D ≤ 0.1 m2/s) as the tritons slow down from 1 MeV to ~0.09 MeV
