Vibration Analysis of KAGRA Cryostat at Cryogenic Temperature
Rishabh Bajpai, Takayuki Tomaru, Nobuhiro Kimura +4
KAGRA uses cryogenics to cool its sapphire test masses down to 20 K to reduce the thermal noise. However, cryocooler vibration and structural resonances of the cryostat couple to t…
High Performance Heat Conductor with Small Spring Constant for Cryogenic Applications
Tomohiro Yamada, Takayuki Tomaru, Toshikazu Suzuki +5
We developed a soft and high thermal conductive heat link for cryogenic applications. The measured maximum thermal conductivity was approximately 18500 W/m/K at 10 K. This spring c…
Evaluation of heat extraction through sapphire fibers for the GW observatory KAGRA
Alexander Khalaidovski, Gerd Hofmann, Dan Chen +9
Currently, the Japanese gravitational wave laser interferometer KAGRA is under construction in the Kamioka mine. As one main feature, it will employ sapphire mirrors operated at a…
