Enhanced Scattering Inherent to "Loss-Cone" Particle Distributions

Abstract

Particle scattering due to a Rosenbluth-Post convective loss-cone instability is calculated using a slab model. This collective contribution to the scattering rate is found to be the classical scattering rate increased by a factor ${\left(\frac{T_i}{T_e}\right)}^{\frac{3}{2}}{\left(\frac{m_e}{m_i}\right)}^{\frac{1}{2}}{\left(\ln \Lambda \right)}^{-1\mathrm{}}\times \left(\mathrm{energy}\mathrm{amplification}\mathrm{of}\mathrm{the}\mathrm{convective}\mathrm{instability}\mathrm{in}\mathrm{the}\mathrm{finite}\mathrm{plasma}\right)$.
