A new seismic isolation system, TAMA Seismic Attenuation System (TAMA-SAS), was installed to TAMA300 in order to improve the sensitivity at low frequencies. Inertial damping is one of the...
A two-dimensional low-frequency vibration attenuator using X-pendulums (2007)
D. Tatsumi, Mark A. Barton, T. Uchiyama, K. Kuroda
We have designed and constructed an improved two dimensional X-pendulum vibrationisolation table. It achieved a lower resonant frequency (7 s) than previous prototypes, and the effects of many...
Joint LIGO and TAMA300 search for gravitational waves from inspiralling neutron star binaries (2006)
Abbott, B., Abbott, R., Adhikari, R., Ageev, A., Agresti, J., Ajith, P., ...
We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange method, we perform an...

Sato, S., Miyoki, S., Telada, S., Tatsumi, D., Araya, A., Ohashi, M., ...
In order to detect the rare astrophysical events that generate gravitational wave (GW) radiation, sufficient stability is required for GW antennas to allow long-term observation. In practice, seismic...
Sato, N., Haruyama, T., Kanda, N., Kuroda, K., Miyoki, S., Ohashi, M., ...
We measured forces applied by an actuator with a YBCO film at near 77 K for the Large-scale Cryogenic Gravitational-wave Telescope (LCGT) project. An actuator consisting of both a YBCO film of 1.6...
Mechanical quality factor of a sapphire fiber at cryogenic temperatures (2000)
Uchiyama, T., Tomaru, T., Tatsumi, D., Miyoki, S., Ohashi, M., Kuroda, K., ...
A mechanical quality factor of $1.1 \times 10^{7}$ was obtained for the 199 Hz bending vibrational mode in a monocrystalline sapphire fiber at 6 K. Consequently, we confirm that pendulum thermal...
