Modulated ECRH has been used to study electron thermal transport in DITE. In most cases the spatial structure of the thermal waves produced is consistent with a simple diffusive transport model in which the heat flux is proportional to the electron temperature gradient, q = -neχe ∇Te. At low density (ne ≈ 1019 m-3) the values of electron thermal diffusivity deduced from modulation experiments (χemod) are ≈ 2.5 m2.s-1, similar to the values deduced from power balance analysis (χePB and sawtooth heat pulse propagation (χest). At higher density (ne ≈ 3 × 1019 m-3) the interpretation of the modulation data is sensitive to details of the ECRH power deposition profile. The high density data are fitted best by assuming that approximately 30% of the ECRH power is deposited with a broad profile with the remainder more localized, in qualitative accordance with ray tracing code predictions. The values of χemod deduced are then ≈ 1.3 m2.s-1, again similar to the values of χePB and χest

変調ECRHを用いて、DITEにおける電子熱輸送を研究した。ほとんどの場合、生成される熱波の空間構造は、熱流束が電子温度勾配に比例する単純な拡散輸送モデル、q = -neχe ∇Te と整合的である。低密度(ne ≈ 1019 m-3)では、変調実験から推定される電子熱拡散係数の値(χemod)は≈ 2.5 m2.s-1であり、パワーバランス解析(χePB)および鋸歯状熱パルス伝播(χest)から推定される値と同程度である。高密度(ne ≈ 3 × 1019 m-3)では、変調データの解釈はECRHパワー堆積プロファイルの詳細に敏感である。高密度データは、ECRHパワーの約30%が広いプロファイルで堆積し、残りがより局所的に堆積すると仮定することで最もよくフィットする。これはレイトレーシングコードの予測と定性的に一致する。その場合に推定されるχemodの値は≈ 1.3 m2.s-1であり、これもχePBおよびχestの値と同程度である。
