The radial electric field profiles are derived from poloidal rotation velocity for a plateau regime plasma heated by a neutral beam in a CHS device. The measured electric field is more negative than the neoclassical prediction especially near the plasma periphery. However, the negative radial electric field is not directly related to the reduction of thermal diffusivity. Physics of Fluids B: Plasma Physics is copyrighted by The American Institute of Physics
