KAGRA 是在日本岐阜县神冈建造的第二代干涉引力波探测器，臂长 3 公里。它现在正处于最后安装阶段，我们称之为 bKAGRA（基线 KAGRA），预计将于 2019 年底开始科学观测。KAGRA 的优势之一是其位于地下至少 200 m 处，可减少低频地震运动并提高探测器的稳定性。另一个优点是它将蓝宝石测试质量镜冷却至低温以减少热噪声。 2018年4月至5月，我们对带有低温测试质量的3公里迈克尔逊干涉仪进行了10天的运行，这是公里级干涉仪首次在低温下运行。在本文中，我们报告了“bKAGRA 第一阶段”操作的结果。我们已经证明了使用低温镜进行 3 公里干涉仪对准和控制的可行性。
KAGRA is a second-generation interferometric gravitational-wave detector with 3 km arms constructed at Kamioka, Gifu, Japan. It is now in its final installation phase, which we call bKAGRA (baseline KAGRA), with scientific observations expected to begin in late 2019. One of the advantages of KAGRA is its underground location of at least 200 m below the ground surface, which reduces seismic motion at low frequencies and increases the stability of the detector. Another advantage is that it cools down the sapphire test mass mirrors to cryogenic temperatures to reduce thermal noise. In April–May 2018, we operated a 3 km Michelson interferometer with a cryogenic test mass for 10 d, which was the first time that km-scale interferometer was operated at cryogenic temperatures. In this article, we report the results of this ‘bKAGRA Phase 1’ operation. We have demonstrated the feasibility of 3 km interferometer alignment and control with cryogenic mirrors.
