要旨

The second generation of gravitational-wave detectors are being built and
tuned all over the world. The detection of signals from binary black holes is
beginning to fulfill the promise of gravitational-wave astronomy. In this work,
we examine several possible configurations for third-generation laser
interferometers in existing km-scale facilities. We propose a set of
astrophysically motivated metrics to evaluate detector performance. We measure
the impact of detector design choices against these metrics, providing a
quantitative cost-benefit analyses of the resulting scientific payoffs.
