KAGRA "Large-scale Cryogenic Gravitational-wave Telescope"

For the first detection of gravitational waves

KAGRA, also known as LCGT, is the largest-scale laser-interferometric telescope project of Japan for the direct detection of gravitational waves, intended to open up a new astronomical frontier, "gravitational-wave astronomy". The project is led by ICRR (Institute for Cosmic Ray Research, University of Tokyo) in cooperation with KEK (High Energy Accelerator Research Organization) and NAOJ. The construction has started in April 2012. KAGRA consists of a modified Michelson interferometer with two 3-km long arms, and the whole system is located in the ground under Kamioka mine. The goal sensitivity of KAGRA corresponds to observing the moment of coalescence of a binary pulsar or black holes beyond 200 Mpc, or detecting several gravitational-wave events a year.

NAOJ ATC is expec ted to be in charge of developing various optical components for KAGRA, and also per forms R&D for future advanced detectors for gravitational astronomy in collaboration with the NAOJ gravitational-wave project office.
