In the fusion devices (tokamaks) using carbonaceous plasma facing components (PFC), erosion as well as re-deposition of carbon atoms have been observed. In the current configuration of Tore Supra (TS), the tokamak located in Cadarache, France, the largest part of PFCs is the toroidal pumped limiter, which is in close interaction with the plasma. It is composed of actively cooled (120°C) carbon fiber composites (CFC) tiles. Analysis of long plasma discharges has pointed out an abnormal deuterium retention which can be due to redeposited layers, as observed on several places on the PFCs [1]. These carbon layers (up to 800 micrometers thick) have been collected and their chemical analysis performed using nuclear reaction analysis shows a D/C deuterium concentration less than 10 % [2]. This low co-deposition rate makes difficult explanation of the particle retention and it is possible that porosity and structural properties of deposits play an important role in deuterimn retention.
