description KAGRA Overview
KAGRA is an underground interferometer observatory situated within the Kamioka mine in Japan. Its location minimizes seismic noise, enhancing its sensitivity for detecting gravitational waves. This allows researchers to study cataclysmic events like black hole mergers and neutron star collisions. The observatory primarily serves scientists investigating fundamental physics and cosmology.
insights Why this score
KAGRA ranks #55 of 206 in the Observatory ranking, behind Daniel K. Inouye Solar Telescope, ahead of Yerkes Observatory.
help KAGRA FAQ
Where is the KAGRA gravitational-wave observatory located?
KAGRA is located deep underground in the Kamioka mine in the Gifu Prefecture of Japan. This subterranean location helps shield the sensitive detectors from seismic noise and vibrations.
How does KAGRA differ from the LIGO observatory?
While LIGO is built in the United States using above-ground facilities, KAGRA is built deep underground to reduce background seismic noise. KAGRA also utilizes sapphire mirrors for its test masses instead of the fused silica used by LIGO to operate at cryogenic temperatures.
When did KAGRA start observing for gravitational waves?
KAGRA began its first official observation run alongside the LIGO and Virgo detectors in early 2020. It is the first major gravitational-wave detector built in Asia to join the global network.
Why is KAGRA built underground?
The primary reason for building KAGRA underground is to isolate it from the seismic vibrations that constantly occur on the Earth's surface. Operating in the Kamioka mine significantly reduces the background noise that could interfere with detecting microscopic spacetime ripples.
