• In the edge plasma of the SUNIST spherical tokamak, the toroidal flow velocity vφ, the poloidal shear layer and the fluctuation-driven particle transport fluxes Γr have been simultaneously measured with Mach probe and Langmuir probe arrays, respectively. The results indicate that the vφ has a radial gradient dvφ/dr. The change of the dvφ/dr positively correlates with both the poloidal shear and the suppression of the Γr. Such coincidence suggests that the toroidal sheared flow may play an important role in the suppression of the edge fluctuation-driven transport in STs.
