Description
KAGRA is the first Gravitational Wave (GW) detector which is located in an underground facility and operates the test masses at cryogenic temperatures. For these two major differences with respect to Advanced LIGO and Advanced Virgo, KAGRA is usually addressed as 2.5G detector and its experience will help to bridge the gap between 2G (aLIGO and AdV) and 3G detectors such as Einstein Telescope, Cosmic Explorer, etc.
One of the biggest differences compared to 2G detectors is the necessity to use crystalline test masses substrates instead of amorphous ones. In this talk, the challenges related to this specific aspect will be reported.
