TAMA 300
TAMA 300 is a gravitational wave detector located on the Mitaka campus of the National Astronomical Observatory of Japan .
It is equipped with an interferometric detector , specifically a Fabry-Pérot interferometer . The arm length of the interferometer is 300 m. The laser beam runs through a tube with a diameter of 400 mm, in which there is a pressure of around 10 −6 Pa. The laser used has a power of 10 W. The lower detection limit was at amplitudes of 10 −21 at a frequency of 1 kHz.
The project started operating in the 1990s; data were collected from 1997 to 2003. From the beginning it was considered unlikely that gravitational waves could be detected with this detector. But it was an important precursor for much larger systems, especially for the KAGRA .
