Future gravitational-wave detectors
---
After the initial successes of Advanced LIGO
and Advanced Virgo, a campaign is underway
increase the sensitivity of the global gravitational-wave
detector network. In the short and medium
term, improvements are planned to bring the
current instruments to their designed sensitivities
and to eventually reach the sensitivity limits
set by the current kilometer-scale detector
facilities. In the long term, planning is
underway for a new generation of detectors,
to be housed in new facilities that can accommodate
interferometers that are 10 km or longer.
Such detectors would achieve sensitivities
that are roughly an order of magnitude better
than the sensitivities of the current generation
of detectors, enabling gravitational-wave
detections at unprecedented rates and high
signal-to-noise ratios.
