Application of the independent component analysis to the iKAGRA data
KAGRA Collaboration, T. Akutsu, M. Ando +244
We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, a…
First cryogenic test operation of underground km-scale gravitational-wave observatory KAGRA
KAGRA Collaboration, T. Akutsu, M. Ando +198
KAGRA is a second-generation interferometric gravitational-wave detector with 3-km arms constructed at Kamioka, Gifu in Japan. It is now in its final installation phase, which we c…
Vibration isolation system with a compact damping system for power recycling mirrors of KAGRA
Y. Akiyama, T. Akutsu, M. Ando +169
A vibration isolation system called Type-Bp system used for power recycling mirrors has been developed for KAGRA, the interferometric gravitational-wave observatory in Japan. A sus…
