Description

The Zhaoshan long-baseline Atom Interferometer Gravitation Antenna (ZAIGA) is a proposed underground long-baseline atom interferometer facility, aiming for experimental research on gravitation and related problems. It will be equipped with long-baseline atom interferometers, high-precision atom clocks, and large-scale gyros. ZAIGA facility will take an equilateral triangle configuration with two 1-km-apart atom interferometers in each arm, a 300-m vertical tunnel with atom interferometers and atom clocks mounted, and a tracking-and-ranging 1-km-arm-length prototype with lattice optical clocks linked by locked lasers. The ZAIGA facility will be used for gravitational-wave detection, ultralight dark matter detection, high-precision test of the equivalence principle, clock-based gravitational red-shift measurement, rotation measurement and gravitomagnetic effect. In this talk, we will give a progress report on ZAIGA.
