Abstract
Predictions of theoretical models for ion and electron heat diffusivity have been
compared against experimentally inferred values of the heat diffusivity profile in the edge
plasma of two H-mode and one L-mode discharge in DIII-D [J. Luxon, Nucl. Fusion, 42,
614 (2002)]. Various widely used theoretical models based on neoclassical, ion
temperature gradient modes, drift Alfven modes and radiative thermal instability modes
for ion transport, and based on paleoclassical, electron temperature gradient modes,
trapped electron modes, and drift resistive ballooning modes for electron transport were
investigated.
