TL;DR: In this paper, the electron cyclotron resonance heating (ECH) power was highly localized on the center of a plasma sustained by neutral beam injection, and the eITB was characterized by a high central electron temperature of 6-8 keV with an extremely steep gradient, as high as 55 keV m−1 and a low electron thermal diffusivity within a normalized average radius ρ≈0.3.
