Agatsuma, Kazuhiro, Arai, Koji, Fujimoto, Masa-Katsu, Kawamura, Seiji, Kuroda, Kazuaki, Miyakawa, Osamu, ...

We report on the current status of CLIO (Cryogenic Laser Interferometer Observatory), which is a prototype interferometer for LCGT (Large scale Cryogenic Gravitational-wave Telescope). LCGT is a...

Direct Measurement of Thermal Fluctuation of High-Q Pendulum (2009)

Agatsuma, Kazuhiro, Uchiyama, Takashi, Yamamoto, Kazuhiro, Ohashi, Masatake, Kawamura, Seiji, Miyoki, Shinji, ...

We achieved for the first time a direct measurement of the thermal fluctuation of a pendulum in an off-resonant region using a laser interferometric gravitational wave detector. These measurements...

Experimental investigation of a control scheme for a tuned resonant sideband extraction interferometer for next-generation gravitational-wave detectors (2008)

Kawazoe, Fumiko, Sato, Shuichi, Leonhardt, Volker, Miyakawa, Osamu, Morioka, Tomoko, Nishizawa, Atsushi, ...

LCGT plans to use tuned RSE as the optical configuration for its interferometer. A tuned RSE interferometer has five degrees of freedom that need to be controlled in order to operate a...

New method for quantitative mapping of metallic elements in tissue sections by electron probe microanalyser with wavelength dispersive spectrometers (2001)

Watanabe, Kouichi, Miyakawa, Osamu, Kobayashi, Masayoshi

In this paper, we have proposed a new method that gives quantitative distributions of metallic elements in a tissue section by electron probe microanalyser equipped with wavelength dispersive...
