ABSTRACT.Electron heat pulse propagation following sawtooth collapse has been simultaneously observed
along two opposite radial directions.For a given flux surface,the arrival of the heat pulse at the high field side
(HFS) is delayed by up to 1 ms as compared with the arrival at the low field side (LFS).The observed delay
agrees with an estimate of the time required for parallel electron heat transport along the magnetic field lines
connecting the corresponding LFS and HFS isobars.This suggests that the primary radial heat transport occurs
on the LFS,whereas the HFS is fed subsequently from the LFS by temperature equilibration along the connecting
magnetic field lines.
1.INTRODUCTION
It is usually assumed that electron heat transport
is governed by a diffusive process across the entire
magnetic surface,and consequently that the electron
heat diffusivity x,(r) is a useful characteristic quantity
to describe this process.Experimentally,x,(r) is
commonly derived from the (quasi-)stationary energy
balance ,Complementing this standard procedure,
perturbation methods have been applied to calculate
the xe values from the radial propagation of transients
on the electron temperature T,and electron density ne
profiles .An intrinsic source of such transients is
the sawtooth collapse occurring in tokamaks under many
discharge conditions.
Previous analyses of the heat pulse propagation
following the sawtooth collapse have been based on
observations along one radial direction only,except for
the most recent analysis They have addressed the
question of whether,and to what extent,the xe values
derived from heat pulse propagation differ from those
obtained from the stationary power balance.
The present paper reports on the simultaneous
observation of heat pulse propagation along two radial
directions in the equatorial plane,that is along both the
high field side (HFS) and the low field side (LFS).The
measured delay between the arrival of the heat pulses
on the same magnetic surface leads to the conclusion
that the observed pattern,initiated by an asymmetric
sawtooth crash,can only be explained by the combined
action of parallel and perpendicular transport.
