KAGRA 是一座新建的引力波望远镜，是一种激光干涉仪，由长 3 公里的臂组成，位于日本岐阜县神冈市。 KAGRA 建在地下，使用低温镜进行操作，有助于减少地震和热噪声。这两项技术有望为引力波望远镜的未来提供方向。 2019年，KAGRA按照设计配置完成了所有安装，我们称之为基线KAGRA。为此，我们在一系列文章中从不同的角度对基线 KAGRA 进行了概述。在这篇文章中，我们介绍了KAGRA的设计配置及其历史背景。
KAGRA is a newly built gravitational-wave telescope, a laser interferometer comprising arms with a length of 3 km, located in Kamioka, Gifu, Japan. KAGRA was constructed under the ground and it is operated using cryogenic mirrors that help in reducing the seismic and thermal noise. Both technologies are expected to provide directions for the future of gravitational-wave telescopes. In 2019, KAGRA finished all installations with the designed configuration, which we call the baseline KAGRA. For this occasion, we present an overview of the baseline KAGRA from various viewpoints in a series of articles. In this article, we introduce the design configurations of KAGRA with its historical background.
