✦ Synopsis

Large scale Cryogenic Gravitational wave Telescope (LCGT) is proposed to detect directly gravitational waves from neutron binary star coalescences at 240 Mpc away from our galaxy with signal-to-noise ration of 10. The designed strain sensitivity is 3 × 10 -24 1/ √ Hz at 100Hz. To realize this sensitivity, LCGT is to be set in a stable and low seismic noise environment such as the Kamioka mine, to have sapphire cryogenic mirrors and suspension fibers, and to utilize broad band RSE technique combining with a power recycling technique. Two identical telescopes are set in the same site to enhance reliable detection. We will introduce the refined LCGT design.
