Abstract

Passing alpha particles in a Helias reactor are well confined if only Coulomb collisions perturb the particle orbits and neoclassical diffusion is the only transport process. In a turbulent plasma close to the beta limit particle orbits can become chaotic and enhanced losses of these particles may arise thus diminishing the alpha particle heating rate. The paper describes the guiding center orbits of passing particles in the magnetic field of the Helias reactor, where islands of the magnetic surface occur at the boundary.
