 Phase 2 of the model removed key assumptions in the Rider analysis by incorporating a self-consistent treatment of the ion energy distribution (Rider assumed a purely Maxwellian distribution) and the power required to maintain the distribution and ion population.The results yielded an energy distribution that was non-thermal but more Maxwellian than monoenergetic.The input power required to maintain the distribution was calculated to be excessive and ion-ion thermalization was a dominant loss channel.
