Electron thermal transport in DIII-D H-mode tokamak plasmas ͓J. L. Luxon, Nucl. Fusion 42, 614 ͑2002͔͒ is investigated by comparing predictive simulation results for the evolution of electron temperature profiles with experimental data. The comparison includes the entire profile from the magnetic axis to the bottom of the pedestal. In the simulations, carried out using the automated system for tran...
