The ETIC Industry Day took place on 15 and 16 February at EGO, the European Gravitational Observatory, that hosts the Virgo interferometer. ETIC Industry Day was a two-day meeting aimed at the Italian business world to discuss opportunities for collaboration in research and technological development for the Einstein Telescope (ET). The event, organized by the INFN Divisions and university departments that are part of the ETIC consortium (Einstein Telescope Infrastructure Consortium) - the project financed with 50 million euros as part of Mission 4 of the PNRR coordinated by the Ministry of University and Research to support the Italian candidacy to host ET – , in collaboration with the Industrial Liaison Officer (ILO) of CERN, saw the participation of over 50 companies and representatives of the industrial world. Proposed and coordinated by INFN, ETIC brings together universities and national research institutions. It will deal with the preparation and implementation of the feasibility study and the characterization of the Italian site identified to host ET, the disused mine of Sos Enattos, in the Nuoro area, and of the creation of a network of research laboratories for the development of technologies that will be adopted by the new gravitational observatory.
