Quasi-linear calculation of ion tails and neutron rates in a D-T plasma due to lower hybrid waves

Abstract

Quasi-linear theory is used to calculate the distribution function and neutron rate of a D-T plasma being heated by a lower hybrid wave. It is shown that Q-values approaching 1 are possible for sufficiently high bulk temperatures and for small deuterium concentrations.

Quasi-linear ion heating by lower hybrid waves

“…Investigations of this kinetic equation have mainly concentrated on the effects of stochasticity on the ion distribution function at a given point, assuming the field distribution to be known [8][9][10][11]. The field reaching the core of the plasma, however, is determined not only by the coupling structure but also by the damping rates due to ion acceleration; these in turn depend on the local field intensity.…”
