The perpendicular spectrum of high-energy particles originally injected tangentially was measured using a neutral particle analyzer (NPA) based on a natural diamond detector (NDD) in the Large Helical Device (LHD). The steady state spectrum showed the dependence on the magnetic configuration, indicating the effect of the orbit loss. An analytical asymptotic solution of the Fokker-Planck equation, taking into account collision terms of coulomb interaction, the fast-ion source term and the orbit loss of the helically trapped and transition particles, is proposed.
