abstract = {Morphology of carbon plasma facing components retrieved
from the TEXTOR tokamak after long operation periods and
exposure to total particle doses exceeding 7 x 10(26) m(-2)
was determined. Emphasis was on the composition and
structure of the erosion zones. Tiles from two limiters-the
main toroidal belt pump ALT-II and auxiliary inner
bumper-were examined using high-resolution microscopy,
surface profilometry, ion beam analysis techniques and
energy dispersive X-ray spectroscopy. The essence of results
regarding the net-erosion zones is following: (i)
microstructure of surfaces is significantly smoother than on
a non-exposed graphite, whereas carbon fibre composites show
similar appearance prior to the exposure and after; (ii)
deuterium retention is 2-5 x 10(21) m(-2); (iii) the
presence of plasma impurity atoms (e.g. metals) is detected
predominantly in small cavities acting as local shadowed
areas on the surface. The results are discussed in terms of
processes of material erosion/re-deposition and tokamak
operation conditions influencing the morphology of wall
components. (c) 2005 Elsevier B.V. All rights reserved.},
