The status of LCGT

Abstract

The current status of LCGT is described. The physical target of LCGT is to detect every year at least one event of gravitational wave signal produced at the coalescence of a binary neutron star. To attain this objective, LCGT is built underground by adopting cryogenic mirrors with a high power laser. To assure the reliable detection, two independent sets of interferometers are installed in a common vacuum system.
