A solution of the Fokker-Planck equation is obtained for the distribution of trapped particles in the magnetic field ripples of an imperfectly axisymmetric Tokamak; the resulting particle flux and the ion heat flux arising from the toroidal drift of such particles are calculated, revising previous estimates which neglected the asymmetry of the ripple profile.
