| Popis: | Combined tests of tungsten mock-ups with thermocyclic test in the electron beam facility with the load up to 50 MW/m² and subsequent irradiation with steady-state plasma load up to 1 MW/m² in PLM device have been carried out to simulate a material degradation under loads expected in a fusion reactor. Cracks of 1–5 microns and more have been formed on the surface of the tungsten during e-beam test. Melted layer observed in the area of e-beam hot spot load. Plasma load led to a formation of nanostructured layers on the surface. |
