Cryogenic suspension design for a kilometer-scale gravitational-wave detector
Takafumi Ushiba, Tomotada Akutsu, Yoichi Aso +43
We report the mirror suspension design for Large-scale Cryogenic Gravitational wave Telescope, KAGRA, during bKAGRA Phase 1. Mirror thermal noise is one of the fundamental noises f…
Angular response of a triangular optical cavity analyzed by a linear approximation method
Satoshi Tanioka, Gui-guo Ge, Keiko Kokeyama +3
A triangular optical cavity is often used as a mode cleaning cavity in precision laser interferometry such as gravitational wave detectors. An alignment sensing and control system…
Design and experimental demonstration of a laser modulation system for future gravitational-wave detectors
Kohei Yamamoto, Keiko Kokeyama, Yuta Michimura +12
Detuning the signal-recycling cavity length from a cavity resonance significantly improves the quantum noise beyond the standard quantum limit, while there is no km-scale gravitati…
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…
Experimental evaluation of the non-classical relation between measurement errors using entangled photon pairs as a probe
Masataka Iinuma, Yutaro Suzuki, Masayuki Nakano +1
We have experimentally evaluated the non-classical relation between measurement errors in a joint measurement of two non-commuting polarizations by using entangled photon pairs as…
The status of KAGRA underground cryogenic gravitational wave telescope
KAGRA Collaboration, T. Akutsu, M. Ando +146
KAGRA is a 3-km interferometric gravitational wave telescope located in the Kamioka mine in Japan. It is the first km-class gravitational wave telescope constructed underground to…
Mirror actuation design for the interferometer control of the KAGRA gravitational wave telescope
Yuta Michimura, Tomofumi Shimoda, Takahiro Miyamoto +36
KAGRA is a 3-km cryogenic interferometric gravitational wave telescope located at an underground site in Japan. In order to achieve its target sensitivity, the relative positions o…
