Abstract

The effects of the radial electric field on the ripple transport in the stellarator/heliotron are studied. The pitch angle dependence of the detrapping frequency is kept and the transport coefficient is calculated for the arbitrary values of Ω_E/ν_eff(Ω_E: E_r×B rotation frequency ν_eff: effective collision frequency of ripple-trapped particles). A simple interpolation formula is derived and the electron energy confinement time is estimated.
