Abstract
ITER-Like Wall Project has been launched at JET in order to perform a
fully integrated test of plasma-facing materials. During the next major
shutdown a full metal wall will be installed: tungsten in the divertor
and beryllium in the main chamber. Beryllium erosion is one of key
issues to be addressed. Special marker tiles have been designed for this
purpose. Test coupons of such markers have been manufactured and
examined. The performance test under high power deposition was carried
in the electron beam facility JUDITH. The results of material
characterization before and after high heat flux loads are presented.
The samples survived, without macroscopic damage, power loads of up to
4.5 MW/m2 for 10 s (surface temperature ∼650 °C) and 50 cyclic loads at 3.5 MW/m2 lasting 10 s each (surface temperature ∼600 °C).
