在神冈矿区开始建造基线长度为100米的克利奥（低温激光干涉仪观测站）。克利奥的隧道已经挖掘，基础设施工程正在进行中。克利奥是LCGT（大型低温引力波望远镜）的最后一步，也是世界上第一个实际建造的低温干涉仪。克利奥的目的是展示LCGT的三个特点中的两个，即利用地下场地的安静和稳定的环境，以及采用低温蓝宝石反射镜来降低热噪声。此外，这是引力波和天体物理学研究人员的一个联合项目。克利奥具有锁定的法布里-珀罗配置，配备环形模式清洁器和低温冷却器，以将蓝宝石镜冷却至20 K。克利奥的噪声水平被设计为跟踪蓝宝石反射镜的热弹性噪声，其变化范围为300 K时的10−18 m Hz− 1/2至20 K时的10−19 m Hz−1/2（约100 Hz）。在ICRR（宇宙射线研究所）建造了一个7米的单臂低温试验设施，而20米的室温干涉仪正在神冈运行。这些原型开发的技术知识将被用来实现克利奥。
Construction of CLIO (cryogenic laser interferometer observatory) with 100 m baseline length has begun in the Kamioka mine. The tunnel for CLIO has been dug and infrastructure work is now in progress. CLIO is the final step to LCGT (large scale cryogenic gravitational wave telescope) and the first practical construction of a cryogenic interferometer in the world. The objective of CLIO is to demonstrate two of three features of LCGT, which are to utilize the quietness and stable environment of the underground site and to adopt cryogenic sapphire mirrors for thermal noise reduction. Also, it is a joint project by gravitational wave and geophysics researchers. CLIO has a locked Fabry–Perot configuration equipped with ring mode cleaners and cryocoolers to cool the sapphire mirrors to 20 K. The noise level of CLIO is designed to trace the thermoelastic noise of sapphire mirrors which varies from 10−18 m Hz−1/2 at 300 K to 10−19 m Hz−1/2 at 20 K around 100 Hz. A 7 m single-arm cryogenic test facility has been built at ICRR (Institute for Cosmic Ray Research), while the 20 m room temperature interferometer is in operation at Kamioka. Technical knowledge developed by these prototypes will be leveraged to realize CLIO.
