Abstract

The characteristics of electron internal transport barriers (eITB) formation were investigated. The experimental investigations were carried out in relation to the electron cyclotron resonance heating (ECH) injection condition by means of diagnostics with high spatial and time resolution. Improvement of thermal transport within the eITB was confirmed by the analysis of energy transport and the transient response of the radiative temperature.
