The effect of magnetic field configurations on plasma flow velocity was investigated by measuring the parallel flow velocity (v(parallel to)) using a charge-exchange recombination spectroscopy during neutral beam injection in three different toroidal mirror configurations of Heliotron J: high, standard and reversed mirror configurations. The magnetic ripple strengths, gamma, for these mirror configurations were gamma = 0.073 m(-1), 0.031 m(-1) and 0.027 m(-1), respectively, at the normalized averaged minor radius rho = 0.07. The magnetic ripple strength is defined as gamma = {<(partial derivative B/partial derivative l)(2)/B-2 >}(1/2), where <...> is the flux surface averaged value and l is the length along the magnetic field line. At rho = 0.07, the parallel flow velocity in the high mirror configuration (v(parallel to) similar to 4 km s(-1)) was 2-3 times smaller than those in the standard and reversed mirror configurations (v(parallel to) similar to 10-12 km s(-1)). An anticipated interpretation is that the difference in the neoclassical damping force contributes to the difference in v(parallel to) among the three mirror configurations.
