A theory is developed for a partially ionized plasma confined by the walls of a cylinder and rotated by an rf field. The steady-state profiles of the electron, ion, and atom velocities are found, with viscosity being taken into account. The electron component is drawn into the rotation by a nonlinear interaction of the field with the plasma, while the heavy particles are swept along by the electron wind. In a sufficiently dense plasma, in which the mean free paths of the electrons, ions, and atoms are small in comparison with the cylinder radius, the ions and atoms are efficiently entrained in the rotation. The neutral component lags behind the ion component only very slightly. The radial profiles of the densities and the corresponding rf currents in the external circuit are found.
