LCGT

LCGT

The Large Scale Cryogenic Gravitational Wave Telescope (LCGT) is a future project of the gravitational wave studies group at the Institute for Cosmic Ray Research (ICRR) of the University of Tokyo. The ICRR was established in 1976 for cosmic ray studies, and is currently working on TAMA 300.

The current plan is for two sets of 3 km arm length laser interferometric gravitational wave detectors to be built in a tunnel of Kamioka mine in Japan. LCGT will detect chirp waves from binary neutron star coalescence at 240 Mpc away with a S/N of 10. The expected number of detectable events in a year is two or three. To achieve the required sensitivity, several advanced techniques will be employed such as a low-frequency vibration-isolation system, a suspension point interferometer, cryogenic mirrors, a resonant side band extraction method, a high-power laser system and so on. LCGT is expected to be operational in 2009.
