Abstract

The influence of the trapped electrons fraction on the growth-rate of the ion temperature gradient (ITG) modes is studied numerically for JET relevant conditions. As a possible mechanism for increasing the ITG mode growth rate with an increase in the fraction of trapped electrons, a shift in the real frequency is assumed that leads to less Landau damping. Another possible mechanism is the destabilizing contribution of dissipation effects. © 2005 Cambridge University Press.
