Abstract |
KAGRA is a laser interferometric gravitational wave detector under construction in Kamioka-mine, Japan. KAGRA interferometer is 3km base-line Fabry-Perot-Michelson, which is placed inside the tunnel under the mountain to reduce the seismic disturbances and to achieve stable environment. KAGRA also employs cryogenic mirror with sapphire substrate to reduce the thermal noise. The excavation of the tunnel had finished at March 2014. We are installing the peripherals: vacuum system, cryostat, vibration isolation system, laser, optics, digital control system and data acquisition, etc. We would like to present the construction status. We also report the commissioning status toward the first operation in normal temperature mirror planned in the end of 2015, which is called as iKAGRA. iKAGRA is not only a first observation of KAGRA, but also an end-to-end test of the whole KAGRA system including data analysis. We will display the recent progress of KAGRA. |
