abstract = {Mutual contamination between C and W, resulting from the
simultaneous use of these materials as plasma facing
components, is simulated by means of a computer simulation
code, Erosion and Deposition based on Dynamic model (EDDY).
W deposition on C rapidly increases the reflection
coefficient for D and C impurity. In comparison between the
calculation and a C-W twin test limiter experiment in
TEXTOR-94, C release from the C side of the limiter is
dominated by reflection of C impurity from the W deposits,
in addition to physical sputtering of C; chemical erosion is
strongly suppressed. Due to the dynamic effect which makes
C-W mixed layer, C deposition on W gradually changes the
reflection coefficient and sputter yields. Formation of a
sharp boundary between erosion and C deposition zones on the
W side of the limiter is well reproduced by simulation.
Local redeposition patterns of C and W on the limiter
surface are also calculated. (C) 2001 Elsevier Science B.V,
