摘要：

Damping of the plasma toroidal velocity owing to parallel viscosity is observed in the Compact Helical System heliotron-torsatron device with tangential neutral-beam injection. The toroidal velocity profile is dominated by perpendicular viscosity when the magnetic-field modulation is weak near the axis. However, parallel viscosity is found to be dominant when the modulation is strong enough, and to increase in proportion to the square of the modulation of the magnetic field. The absolute values of the viscosity agree with the neoclassical prediction within a factor of 3.
