Description
The erosion characteristics of the carbon based divertor armor tiles in the JT-60 divertor are overviewed. The results show that the sputtering yield of the strike-point area is 20% lower than that of the bulk material. On the other hand, the sputtering yield of the tiles with redeposited layers is 10-20% higher than that of the bulk material. The distribution of tritium inventory in the JT-60 divertor armors is also reported. (author)
