KAGRA是一种低温干涉引力波望远镜，用于直接探测来自天文来源的引力波。为了获得最佳的灵敏度，最困难的挑战之一是将反射镜冷却到20K以减少热噪声。我们开发了四个低温恒温器和十六个非常低振动的低温冷却器来实现我们的目的。本文介绍了低温设计和制造的概况，以及低温恒温器和低温冷却器装置的低温性能测试结果。
KAGRA is the cryogenic interferometric gravitational wave telescope designed for the direct detection of gravitational waves from the astronomical sources. To achieve the best sensitivity, one of the most difficult challenges is cooling the mirrors to 20K to reduce the thermal noise. We developed four cryostats and sixteen very-low-vibration cryocooler units to accomplish our purpose. In this paper, we describe the outline of the cryogenic design and fabrication, and the results of the cryogenic performance test of the cryostats and cryocooler units.
