A brief analysis to Taiji: Science and technology

TLDR

Space-based GW detectors, such as Taiji, are more sensitive to low-frequency signals (0.1 mHz–1 Hz) than ground-based instruments, and the mission has evolved from a 2008 preliminary study to a sophisticated design. The paper provides a concise overview of the preliminary analysis and preparatory work for Taiji’s technology. The study reviews Taiji’s key technologies and R&D efforts, detailing how the mission’s design targets low-frequency GW sources.

Abstract

The space gravitational wave (GW) antennae is more sensitive to the lower frequency GW signals compare with the ground-based GW detectors. The space mission Taiji is designed to detect the GW sources within frequencies between 0.1 mHz and 1 Hz. A preliminary study of Taiji was started in 2008. Up to now, a sophisticated mission design of Taiji have gradually taken shape. The research and development of the key technologies for Taiji is now officially launched. A brief introduction to the analysis and the pre-work of the Taiji technology are given here.
