Large-scale Cryogenic Gravitational Wave Project (KAGRA)

Institute for Cosmic Ray Research, the University of Tokyo, is preceding KAGRA that is Large-scale Cryogenic Gravitational wave telescope, with over 60 universities and institutes in the world. One characteristic aspects of KAGRA is that it is constructed over 200 meter underground to gain merits of low seismic noise that is expected to bring stable continuous operation and better data quality. The other aspects are that KAGRA utilizes cryogenic mirrors and suspensions (~20 K) to reduce their thermal noises that are the final barrier to reach the targeted sensitivity. KAGRA targets to detect GWs from binary neutron star coalescences at the rate of several events per a year around 2017 ~ 2018. KAGRA project home page is http://gwcenter.icrr.u-tokyo.ac.jp.
