KAGRA is a 3-km interferometric gravitational wave telescope located in the<br />
Kamioka mine in Japan. It is the first km-class gravitational wave telescope<br />
constructed underground to reduce seismic noise, and the first km-class<br />
telescope to use cryogenic cooling of test masses to reduce thermal noise. The<br />
construction of the infrastructure to house the interferometer in the tunnel,<br />
and the initial phase operation of the interferometer with a simple 3-km<br />
Michelson configuration have been completed. The first cryogenic operation is<br />
expected in 2018, and the observing runs with a full interferometer are<br />
expected in 2020s. The basic interferometer configuration and the current<br />
status of KAGRA are described.
