Abstract
This paper presents scientific and technical issues
related to the development of erosion-deposition
diagnostic tools for JET operated with the ITER-Like
Wall: beryllium and tungsten marker tiles and several
types of wall probes installed in the main chamber and in
the divertor. Markers tiles are the standard limiter and
divertor components additionally coated first with a thin
sandwich of Ni-Be and Mo-W for, beryllium and tungsten
markers, respectively. Both types of markers are embedded
in regular arrays of limiter and divertor tiles. Coated
W-Be probes are also inserted in the Be-covered Inconel
cladding tiles on the central column. Other types of
erosion-deposition diagnostic tools are: rotating
collectors, deposition traps, louver clips, quartz
microbalance and mirrors for the First Mirror Test at JET
for ITER. The specific role of these tools is discussed
in detail.
