Microstructure, mechanical properties and residual stress of welded stainless-steel jackets for React & Wind conductor in EU-DEMO

Within the framework of the EuroFusion WPMAG project, an automatic laser-welding line was constructed to produce a 1 km long, empty stainless steel jacket demonstrator for the React & Wind (RW) conductor for EU-DEMO. Four 500 m long C-profiles made of 316L austenitic stainless steel were fabricated from ~8 m long sections using the manual TIG (Tungsten Inert Gas) welding method. A series of experimental investigations was carried out on the welded samples, including ferrite content measurements, microhardne

Transparent dielectric elastomer actuator used as tunable optical grating

Samuel Rosset

In this work, a transparent dielectric elastomer actuator is integrated into a tunable transmission grating. A 13 micron-thick silicone membrane has been sandwiched between two 750 nanometer-thick transparent ionogel electrodes to fabricate a transparent dielectric elastomer actuator. By structuring the top transparent ionogel electrode into a sinusoid grating profile, with 2 µm period, the transparent dielectric elastomer actuator is transformed into a tunable transmission grating. The structured stretchab
