The search for gravitational radiation with optical interferometers is gaining momentum worldwide. Beside the VIRGO and GEO gravitational wave observatories in Europe and the two LIGOs in the United States, which have operated successfully during the past decade, further observatories are being completed (KAGRA in Japan) or planned (ILIGO in India). The sensitivity of the current observatories, although spectacular, has not allowed direct discovery of gravitational waves. The advanced detectors (Advanced LIGO and Advanced Virgo), at present in the development phase, will improve sensitivity by a factor of 10, probing the universe up to 200 Mpc for signal from inspiraling binary compact stars. This book covers all experimental aspects of the search for gravitational radiation with optical interferometers. Every facet of the technological development underlying the evolution of advanced interferometers is thoroughly described, from configuration to optics and coatings, and from thermal compensation to suspensions and controls. All key ingredients of an advanced detector are covered, including the solutions implemented in first-generation detectors, their limitations, and how to overcome them. Each issue is addressed with special reference to the solution adopted for Advanced VIRGO, but constant attention is also paid to other strategies, in particular those chosen for Advanced LIGO.

Massimo Bassan is Associate Professor of Physics at University of Rome Tor Vergata. His research focuses mainly on gravitational waves: he built the first Italian prototype of the interferometer, took part in the development of resonant cryogenic antennas, and he is currently involved in the spatial mission LISA (Laser Interferometer Space Antenna) of ESA. He is also member of the Executive Board of the Virgo-EGO Scientific Forum (VESF) and coordinates the VESF schools on gravitational waves.
