The Current Status and Future Prospects of KAGRA, the Large-Scale Cryogenic Gravitational Wave Telescope Built in the Kamioka Underground
KAGRA is a gravitational-wave (GW) detector constructed in Japan with two unique key features: It was constructed underground, and the test-mass mirrors are cooled to cryogenic temperatures.These features are not included in other kilometer-scale detectors but will be adopted in future detectors such as the Girls Jewelry Einstein Telescope.KAGRA pe
