Ce papier présente une synthèse des études menées sur le tokamak JET afin de clarifier la physique des barrières internes de transport. Les résultats expérimentaux, de modélisation et de théorie sont revus. Plusieurs points sont discutés, notamment la question des mécanismes en jeu pour la formation des barrières et la nature de la transition, le rôle du cisaillement magnétique, la position et la largeur des barrières, et le pouvoir de prédiction des modèles de transport turbulent.

This article presents an overview of the studies carried out at JET to clarify the physics of Internal Transport Barriers. Results of dedicated experiments, modelling and theory are reported. Several issues are discussed, namely the question of the dominant mechanisms for barrier formation and the nature of the transition, the role of magnetic surfaces in barrier triggering, the question of radial location and width of barriers, and the predictive capability of transport and turbulence modelling.
