Title: Comparison of theoretical and experimental heat diffusivities in the DIII-D edge plasma
Author: Stacey, Weston M.
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-modes 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 Alfvén 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.
