Transport of iron in TFTR discharges heated by 6.7 MW of co-injected neutral beam power has been studied by spatially resolved charge exchange recombination spectroscopy in the visible region of the spectrum. The time evolutions of the densities of Fe24+ and Fe23+ ions following injection of iron are modelled by the neoclassical flux plus a moderately hollow diffusivity, increasing linearly from 1.3 m2/s on axis to 2.4 m2/s at the plasma edge. For r/a > 0.5, the iron diffusivity is significantly smaller than the helium diffusivity measured in identical discharges, while it is larger in the region immediately surrounding the plasma axis.

TFTR放電における鉄の輸送が、6.7 MWの同方向入射中性粒子ビーム出力によって加熱された放電において、可視領域の電荷交換再結合分光法による空間分解測定によって研究された。鉄注入後のFe24+およびFe23+イオンの密度の時間発展は、新古典フラックスに加えて、軸上で1.3 m2/sからプラズマ端で2.4 m2/sまで線形に増加する中程度に中空な拡散係数によってモデル化された。r/a > 0.5では、鉄の拡散係数は同一の放電で測定されたヘリウム拡散係数よりも有意に小さく、一方でプラズマ軸の直近領域ではより大きい。
