Demonstration of length control for a filter cavity with coherent control sidebands
Naoki Aritomi, Yuhang Zhao, Eleonora Capocasa +22
For broadband quantum noise reduction of gravitational-wave detectors, a frequency-dependent squeezed vacuum field realized using a filter cavity is the most promising technique an…
Improving the stability of frequency dependent squeezing with bichromatic control of filter cavity length, alignment and incident beam pointing
Yuhang Zhao, Eleonora Capocasa, Marc Eisenmann +21
Frequency dependent squeezing is the main upgrade for achieving broadband quantum noise reduction in upcoming observation runs of gravitational wave detectors. The proper frequency…
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…
An arm length stabilization system for KAGRA and future gravitational-wave detectors
T. Akutsu, M. Ando, K. Arai +198
Modern ground-based gravitational wave (GW) detectors require a complex interferometer configuration with multiple coupled optical cavities. Since achieving the resonances of the a…
Torsion-bar antenna: a ground-based mid-frequency and low-frequency gravitational wave detector
Tomofumi Shimoda, Satoru Takano, Ching Pin Ooi +4
Expanding the observational frequency of gravitational waves is important for the future of astronomy. Torsion-Bar Antenna (TOBA) is a mid-frequency and low-frequency gravitational…
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…
Seismic Cross-coupling Noise in Torsion Pendulums
Tomofumi Shimoda, Naoki Aritomi, Ayaka Shoda +2
Detection of low frequency gravitational waves around 0.1 Hz is one of the important targets for future gravitational wave observation. One of the main sources of the expected sign…
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…
