  Sharp temperature gradients in a magnetically confined plasma can lead to
turbulent motion of the plasma. This turbulence in turn enhances the transport
of heat across magnetic field lines. The enhanced transport impacts the
temperature differential that can be sustained in magnetic islands between the
island centre and its periphery. It is shown here that, by limiting this
temperature differential, this enhanced transport can have a profound influence
on the extent to which the RF current condensation effect stabilises the island
growth. Interestingly, because the heat transport is no longer simply linear in
the temperature gradient, the RF current condensation effect also exhibits
entirely new hysteresis phenomena.
