abstract = {During detachment a structure of strongly enhanced density
develops close to the inner target. Its dynamics is
approximated by those of radiative fluctuations appearing at
a similar position and studied by means of a
time-delay-estimation technique in the ASDEX Upgrade
tokamak. Compared to theory the dynamics can be described as
follows: at increasing density the ionization front moves
upstream to reduce ionization radiation in order to balance
the increased recombination radiation. The recombination
zone stays close to the target strike point. The parallel
motion of the ionization front is determined by the
perpendicular neutral motion. The divertor nose constitutes
an obstacle for the perpendicular neutral flux from the
target to the region above the X-point. Passing into this
shadow the neutral flux above the X-point is strongly
reduced, the ionization front fades away and the heat flux
from upstream can increase the temperature in the
recombination region, subsequently reducing recombination
and reforming an ionization front below the X-point. A
cyclic reformation of the ionization front propagating from
below to above the X-point occurs leading to a fluctuation
as observed in the experiment.},
