Advanced Virgo: AN Update
Abstract
Significant progress has been made in recent years on the development of gravitational wave detectors. Several km-scale interferometers have already operated at interesting sensitivity levels. In particular, the interferometric detector for gravitational waves Virgo completed its fourth science run in August 2011, when the upgrade toward the second-generation detector Advanced Virgo started. This major upgrade is planned to be completed by 2015. The expected final sensitivity of Advanced Virgo is about ten times better than the sensitivity reached by its predecessor. Many of the components of the detector will be changed to meet this goal, including new core optics, a more powerful laser, an improved vacuum system, the implementation of the signal-recycling technique. In this paper the description of the project and the expected schedule are presented.
