Description
Recent results obtained in TCABR (Tokamak Chauffage Alfven Bresilien) [J. H. F. Severo, I. C. Nascimento, V. S. Tsypin, and R. M. O. Galvao, Nucl. Fusion 43, 1047 (2003)] show a nonmonotonic variation of the poloidal rotation velocity at the position of major magnetic islands. In this paper, the associated effect of the magnetic islands on the radial profile of the electron temperature is discussed. Analytical temperature profiles are used to analyze the experimental data obtained with electron cyclotron emission radiometry. It is shown that the competition between strong anomalous perpendicular diffusive transport and parallel heat convection is the dominant mechanism for the oscillations observed in the radial profile of the electron temperature in TCABR
