 note = {The radial electric field structure in the fusion reactor of the Torsatron/Heliotron configuration is discussed taking into account the effects of the orbit loss of alpha particles.  It was found that the direct loss of alpha-particles has small influence on the profile of the radial electric field.  The trapping efficiency of the alpha particle is also evaluated by using the self-conistent radial electric field.},
