 note = {The radial electric field profiles derived from poloidal rotation velocity are compared with neoclassical estimates for a plateau regime plasma heated by tangentially injected neutral beam in CHS heliotron/torsatron device. The measured electric field (E_r) is more negative than the neoclassical prediction especially near the plasma periphery. A gradient of radial electric field (partial E_r/partial r) in this region is found to be more negative in the plasma with higher electron density. Although the corresponding poloidal rotation velocity is too small to trigger the L/H transition, these negative E_r and partial E_r/partial r  are associated with a reduction of thermal electron conductivity.},
