abstract = {The identification of the sources of atomic tungsten and
the measurement of their radiation distribution in front of
all plasma-facing components has been performed in JET with
the help of two digital cameras with the same
two-dimensional view, equipped with interference filters of
different bandwidths centred on the W I (400.88 nm)
emission line. A new algorithm for the subtraction of the
continuum radiation was successfully developed and is now
used to evaluate the W erosion even in the inner divertor
region where the strong recombination emission is dominating
over the tungsten emission. Analysis of W sputtering and W
redistribution in the divertor by video imaging spectroscopy
with high spatial resolution for three different magnetic
configurations was performed. A strong variation of the
emission of the neutral tungsten in toroidal direction and
corresponding W erosion has been observed. It correlates
strongly with the wetted area with a maximal W erosion at
the edge of the divertor tile.},
