 note = {The GIOTA code [1] has been applied to clarify the configuration dependence of ripple transport properties in LHD. The effective helical ripple (ε_eff), as a measure of the level of ripple transport, is calculated with a wide range scan of magnetic axis position, (R_ax) and plasma beta value (β). Our results show that ε_eff takes a minimum value in a wide radial portion around the configuration with R_ax = 3.53-3.55 m at vacuum. It is also revealed that ε_eff decreases as β is increased for configurations with R_ax of less than the above mentioned range.},
