Chirping Alfvén eigenmodes drive
convective and diffusive transport
 TAE experiment on MAST is modeled by
1D kinetic simulation
Spectrogram of
magnetic perturbation
 The particle flux in 1D velocity space,
which translates to radial transport in 3D,
is analyzed.
 The gradient/flux relation shows that
chirping bursts yield both diffusive and
convective transport, with
 The diffusive contribution is not
quasilinear, since there is only one wave.
