The ITER reference materials have been tested separately in tokamaks,
plasma simulators, ion beams and high heat flux test beds. In order to perform
a fully integrated material test JET has launched the ITER-like Wall Project
with the aim of installing a full metal wall during the next major shutdown.
As a result of R&D projects in 2005–2006, bulk tungsten tiles are foreseen at
the outer horizontal target and tungsten coating at the other divertor tiles.
In some regions of the main chamber, beryllium coated Inconel tiles and bulk
beryllium tiles are utilised which include marker tiles as erosion
diagnostics. This paper gives an overview of the R&D carried out in the frame
of the ITER-like Wall Project on the development of an inertially cooled bulk
tungsten tile design and the characterization of tungsten and beryllium
