Full‐f gyrokinetic simulations starting from real experimental TEXTOR profiles are shown to include all the physics ingredients to maintain the steep density profile in H‐mode. For L‐mode profiles, strong geodesic acoustic modes (GAMs) are observed together with strongly correlated oscillatory particle fluxes which lead to profile relaxation.
