Accelerator mass spectrometry (AMS) and the full combustion method (FCM) followed by liquid scintillation counting were applied to quantitatively determine the tritium retention in the tungsten-coated carbon fibre composites (CFC), in comparison to uncoated CFC tiles from the JET divertor. The tiles were adjacent and exposed to plasma operations between 2007 and 2009. The tritium depth profiles are showing that the tritium retention on the W-coated tile was reduced by a factor of 13.5 in comparison to the uncoated tile whereas the bulk tritium concentration is approximately the same for both tiles.

加速器質量分析(AMS)および液体シンチレーション計数(LSC)を伴う全燃焼法を適用し、JETダイバータからの無被覆炭素繊維複合材(CFC)タイルと比較して、タングステン被覆炭素繊維複合材(CFC)におけるトリチウム保持量を定量的に測定した。これらのタイルは隣接して配置され、2007年から2009年の間にプラズマ運転に曝露された。トリチウム深部プロファイルは、無被覆タイルと比較して、W被覆タイルではトリチウム保持量が13.5倍減少したことを示している。一方、バルクのトリチウム濃度は両タイルでほぼ同程度であった。
