Reduction of thermal fluctuations in a cryogenic laser interferometric gravitational wave detector
Takashi Uchiyama, Shinji Miyoki, Souichi Telada +14
The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first ti…
Current status of the CLIO project
K Yamamoto, T Uchiyama, S Miyoki +27
CLIO (Cryogenic Laser Interferometer Observatory) is a Japanese gravitational wave detector project. One of the main purposes of CLIO is to demonstrate thermal-noise suppression by…
Current status of Japanese detectors
Daisuke Tatsumi, Ryutaro Takahashi, Koji Arai +29
Current status of TAMA and CLIO detectors in Japan is reported in this article. These two interferometric gravitational-wave detectors are being developed for the large cryogenic g…
Measurement of the mechanical loss of a cooled reflective coating for gravitational wave detection
Kazuhiro Yamamoto, Shinji Miyoki, Takashi Uchiyama +13
We have measured the mechanical loss of a dielectric multilayer reflective coating (ion-beam sputtered SiO and TaO) in cooled mirrors. The loss was nearly independent o…
Thermal lensing in cryogenic sapphire substrates
Takayuki Tomaru, Toshikazu Suzuki, Shinji Miyoki +6
We report the reduction of the thermal lensing in cryogenic sapphire mirrors, which is planed to be used in the Large scale Cryogenic Gravitational wave Telescope (LCGT) project. W…
Mechanical quality factor of a sapphire fiber at cryogenic temperatures
T. Uchiyama, T. Tomaru, D. Tatsumi +6
A mechanical quality factor of was obtained for the 199 Hz bending vibrational mode in a monocrystalline sapphire fiber at 6 K. Consequently, we confirm that pe…
