Comparison of toroidal viscosity with neoclassical theory

Toroidal rotation profiles are measured with charge exchange spectroscopy for a plasma heated with tangential neutral beam injection ͑NBI͒ in the Compact Helical System ͑CHS͒ heliotron/torsatron device ͓Ida et al., Phys. Rev. Lett. 67, 58 ͑1991͔͒ to estimate the toroidal viscosity. The toroidal viscosity derived from the toroidal rotation velocity shows good agreement with the neoclassical toroidal viscosity plus the perpendicular viscosity ( Ќ ϭ2 m 2 /s).
