GINGER

We outline the scientific objectives, the experimental layout, and the collaborations envisaged for the GINGER (Gyroscopes in general relativity) project. The GINGER project brings together different scientific disciplines aiming at building an array of ring laser gyroscopes (RLGs), exploiting the Sagnac effect, to measure continuously, with sensitivity better than pico-rad/s, large bandwidth (ca. 1 kHz), and high dynamic range, the absolute angular rotation rate of Earth. We address the feasibility of the apparatus with respect to the ambitious specifications above, as well as prove how such an apparatus, which will be able to detect strong earthquakes, very weak geodetic signals, as well as general relativity effects like Lense–Thirring and de Sitter, will help scientific advancements in theoretical physics, geophysics, and geodesy, among other scientific fields.
