title = "Measurements of electron temperature and density fluctuations and comparison to gyrokinetic simulations",
abstract = "Profiles (0.3 < ρ < 0.9) of electron temperature and density fluctuations in a tokamak have been measured simultaneously and the results compared to nonlinear gyrokinetic simulations. Electron temperature and density fluctuations measured in neutral beam-heated, sawtooth-free L-mode plasmas in DIII-D are found to be similar in frequency and normalized amplitude, with amplitude increasing with radius. At ρ = 0.5, nonlinear gyrokinetic simulation results match experimental heat diffusivities and density fluctuation amplitude but overestimate electron temperature fluctuation amplitude and particle diffusivity. In contrast, the simulations at ρ = 0.75 do not match either the experimentally derived transport properties or the measured fluctuation levels.",
