A research laboratory to study the technologies and materials needed to detect gravitational waves will open in Rovigo. The announcement was made by Giacomo Ciani and Marco Bazzan, professors at the Department of Physics and Astronomy at the University of Padua. The Comet (Coating materials for Einstein Telescope) laboratory will open in the Polesine City Service Center, which will thus take on a role more related to scientific research. The center is funded with NRP funds, will be operational by mid-2025, and is part of the Einstein Telescope network of research laboratories. In particular, Comet will be engaged in the study of new glass, new optical coatings for use in the mirrors of next-generation interferometers. It will house environments designed to carry out this research, in particular a high-cleaning room -the "clean room" - where the machines that will produce the coatings will be operational; there will also be a chemical laboratory and another one for studying the coatings.
