Isotope mass scaling of AE damping rates in the JET tokamak plasmas

Abstract [en]

The damping of radially extended Alfven eigenmodes in tokamak plasmas is investigated in JET discharges with different ion mass. The comparison of damping measurements with predictions of a gyro-kinetic model indicates that mode conversion into kinetic Alfven waves is the dominant damping mechanism for Alfven eigenmodes in the plasma core.
