A study of reduction of ion thermal diffusivity in the neutral-beam-heated plasmas in the large helical device was performed. The thermal diffusivity was associated with the transition of the radial electric field. There was a good agreement of the values of radial electric field with the neoclassical theory. There was significant increase of electron temperature and a clear reduction of electron thermal diffusivity in the plasma core in the electron root.
