Description
Recent results regarding the formation of co-deposits, fuel accumulation and overall material transport at the TEXTOR tokamak are described. Two categories of brittle flaking co-deposits were identified: (i) smooth stratified layers of a thickness of up to 50 mm and a fuel content of up to 16 at. %, (ii) granular and columnar structures reaching 1 mm in thickness and containing around 0.5 at. % of fuel species. They were formed on the blades of the toroidal belt pump limiter (∼15000 s of plasma operation) and on the neutraliser plates of this limiter (∼90000 s), respectively. A comparison is made to the fuel inventory measured in other controlled fusion devices with carbon walls
