    AnnotationThis work is focused on the material migration into gaps between tiles and into castellation grooves on plasma-facing components from JET: water-cooled Mk-I divertors and belt limiter blocks. The results show that co-deposition occurs up to a few cm deep in the gaps between the Mk-I tiles and fuel inventory in the the CFC tiles gaps exceeds that on plasma-facing surfaces by up to a factor of 2 Implications of these results for a next-step device are addressed and the transport mechanism into the gaps is briefly discussed.
