Title:

Effect of Alpha Particles on Radial Electric Field Structure in Torsatron / Heliotron Reactor

Abstract:

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.
