Abstract
Zeff profile analysis has been carried out in a low-density and high-Ti discharge with carbon pellet injection. The evolution of the Zeff profile shows a centrally peaked profile just after the pellet injection while the profile gradually returns to an original flat profile as a function of time. Comparison between the evolution of Zeff and Ti profiles in the plasma center strongly suggests that there is a positive relation between Zeff and Ti.
