Advanced LIGO: a second-generation gravitational-wave detector
David Shoemaker
MIT
Gravitational wave detectors, using the principle of laser interferometry
to sense the motion of effectively free test masses, have promise to
make both a direct detection and to lead to a new gravitational-wave
astronomy of observation of violent astrophysical events. Initial LIGO
provided new upper limits for gravitational-wave flux, but no signals
have yet been identified in the data. Advanced LIGO will deliver a key
factor of 10 improvement in the sensitivity, and should make regular
detections once commissioned. The instrument science, at the frontier
of precision measurement, will be discussed. Installation is underway;
observation is planned to start in 2015.
