Material that can withstand conditions in diverter of fusion reactor

Our institute was partner in European project ExtreMat in years 2004 - 2010. We coordinated subproject "Heat Sink Materials" involing 16 European partners.  It overall objective was development of novel heat sink composite materials for extreme loading conditions.

We were successful and we managed to develop a new composite material based on copper reinforced by tungsten fibres, in our institute for a heat sink solution. The new material has excellent structural and dimensional stability and can sustain extreme heat flux. It can be used in divertors of new generation of fusion reactors (see ITER, the current project of fusion reactor) and in other applications.
