Investigation of crackling noise in the vibration isolation systems of the KAGRA gravitational wave detector
Yuhang Zhao, Shin Kirii, Yingtao Liu +3
Gravitational wave detectors, such as KAGRA, require complex mirror suspension systems to reach high sensitivity. One particular concern in these suspensions is the presence of cra…
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…
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…
Conduction Effect of Thermal Radiation in a Metal Shield Pipe in a Cryostat for a Cryogenic Interferometric Gravitational Wave Detector
Takayuki Tomaru, Masao Tokunari, Kazuaki Kuroda +13
A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational…
Cryogenic measurement of the optical absorption coefficient in sapphire crystals at 1.064(micro)m for the Large-scale Cryogenic Gravitational wave Telescope
Takayuki Tomaru, Takashi Uchiyama, Daisuke Tatsumi +6
We have applied laser calorimetry to the measurement of optical absorption in mono-crystalline sapphire at cryogenic temperatures. Sapphire is a promising candidate for the mirror…
