EXPERIMENTAL TESTING AND THEORETICAL ANALYSIS OF SAMPLES OF A DIVERTOR PLATE CONCEPT FOR NET
Because of its main function of plasma impurity control, the divertor is submitted to high thermal fluxes, severe sputtering rates and electromagnetic forces. The present proposal for the divertor plate is the following: 1) W-5Re for the armour; 2) Cu for the heat sink. This choice is due to the low sputtering rate and favourable high temperature mechanical properties of the W-5Re, and the high thermal conductivity of copper. The experimental work involves the following items: 1) definition of a standard procedure for a W-5Re/Cu joint; 2) characterization of the bond; 3) testing of specimens in order to analyse the thermal conductivity properties of the joint and its mechanical behaviour under thermal cycling loads; 4) analyses of the characteristics of the bond after the tests.
