Proof-of-principle demonstration of a Polarization-Circulation Speed Meter
Yohei Nishino, Tomotada Akutsu, Yoichi Aso +3
We present the first experimental implementation of a polarization-circulation speed meter. In our experiment, the interferometer was reduced to a single-cavity configuration with…
Identification of Noise-Associated Glitches in KAGRA O3GK with Hveto
T. Akutsu, M. Ando, M. Aoumi +148
Transient noise ("glitches") in gravitational wave detectors can mimic or obscure true signals, significantly reducing detection sensitivity. Identifying and excluding glitch-conta…
Photon Calibration Performance of KAGRA during the 4th Joint Observing Run (O4)
Dan Chen, Shingo Hido, Darkhan Tuyenbayev +9
KAGRA is a kilometer-scale cryogenic gravitational-wave (GW) detector in Japan. It joined the 4th joint observing run (O4) in May 2023 in collaboration with the Laser Interferomete…
Theoretical Characteristics of a three-point Roberts Linkage
Munetake Otsuka, Kohei Mitsuhashi, Ryutaro Takahashi +3
The Roberts linkage is recognized for enabling long-period pendulum motion in a compact format. Utilizing this characteristic, we are developing a three-point Roberts linkage for v…
Control Scheme for Polarization Circulation Speed Meter Using a Dual-Retardation Waveplate
Yohei Nishino, Tomotada Akutsu, Yoichi Aso +1
In interferometric gravitational wave detectors, quantum radiation pressure noise, which is a back action of the measurement, will limit their sensitivities at low frequencies. Spe…
Input optics systems of the KAGRA detector during O3GK
T. Akutsu, M. Ando, K. Arai +246
KAGRA, the underground and cryogenic gravitational-wave detector, was operated for its solo observation from February 25th to March 10th, 2020, and its first joint observation with…
