TL;DR
The paper discusses the GINGER project, a large-scale ring-laser array designed to test fundamental physics by measuring relativistic effects on space-time at an underground laboratory.
Contribution
It introduces the GINGER project, detailing its design, current progress, and future plans for a three-dimensional ring-laser array to test relativistic effects.
Findings
Preliminary measurements with GP2 and GINGERino are underway.
GINGER is expected to be operational within a few years.
The project aims to measure de Sitter and Lense-Thirring effects.
Abstract
After reviewing the importance of light as a probe for testing the structure of space-time, we describe the GINGER project. GINGER will be a three-dimensional array of large size ring-lasers able to measure the de Sitter and Lense-Thirring effects. The instrument will be located at the underground laboratory of GranSasso, in Italy. We describe the preliminary actions and measurements already under way and present the full road map to GINGER. The intermediate apparatuses GP2 and GINGERino are described. GINGER is expected to be fully operating in few years.
