Post mortem analyses of tiles removed from the JET MkII HD divertor in 2007 are presented. The results indicate an increase in deposition at the outer plasma shadowed region of the divertor, not seen prior to 2004 and indicating a shift away from the asymmetric picture of net deposition at the inner divertor compared with no overall deposition or erosion at the outer divertor. Surface analysis of the inner and outer vertical divertor tiles are largely the same as observed previously, however a notable increase in Be composition on the inner and outer floor tiles is observed. Analysis of campaign averaged plasma configurations can provide some explanation for the changes in deposition/erosion characteristics observed however further input can be provided by diagnostics and 13C puffing experiments from which time resolved data to be obtained. In particular, data from rotating collector diagnostics are presented.
