Abstract
Results show that steady-state solutions of the bounce-averaged Fokker-Planck equation in which the Maxwellian ion population---absolutely confined in the electrostatic well---is dominant correspond to lowest ion recirculation powers (and hence highest fusion energy gains). Also, it is shown that the square-well assumption---used ubiquitously in previous analytical estimates of IEC fusion energy gain limits---is in fact a pessimistic one, and that more realistic parabolic-like wells are much more efficient operating regimes with fusion power to ion input power ratios >100 have been identified.
