Large-scale Cryogenic Gravitational wave Telescope project and RD

摘要

The Large-scale Cryogenic Gravitational wave Telescope (LCGT) project is the project constructing the km-scale gravitational wave detector in Japan succeeding the TAMA project, which adopts cryogenic mirrors with a higher power laser and aims to improve the sensitivity of the existing gravitational wave projects by more than ten times. We are planing to build it in an underground site near Super-KAMIOKANDE in Kamioka mine. If its target sensitivity is attained, we will be able to catch a few events of coalescence of neutron-star binaries per month.
