The Virgo interferometer, a detector for gravitational waves located near Pisa in Italy, will soon be upgraded to become the next-generation detector Advanced Virgo. Advanced Virgo will be approximately ten times more sensitive than Virgo, with a design strain sensitivity better than 1023/vHz near 100 Hz. This is expected to enable regular detections of gravitational waves and to yield significant astrophysical results. Many of the components of the detector will be changed for this upgrade. These changes include new core optics, a more powerful laser system, the signal-recycling technique, the use of homodyne detection at the output port, and an improvement of the vacuum system. The existing seismic isolation system in Virgo will be re-used. Advanced Virgo will form part of a global network of advanced gravitational wave detectors along with Advanced LIGO, GEO HF, and LCGT.

Abstract
The Virgo interferometer, a detector for gravitational waves located near Pisa in Italy, will soon be upgraded to become the next-generation detector Advanced Virgo. Advanced Virgo will be approximately ten times more sensitive than Virgo, with a design strain sensitivity better than 1023/vHz near 100 Hz. This is expected to enable regular detections of gravitational waves and to yield significant astrophysical results. Many of the components of the detector will be changed for this upgrade. These changes include new core optics, a more powerful laser system, the signal-recycling technique, the use of homodyne detection at the output port, and an improvement of the vacuum system. The existing seismic isolation system in Virgo will be re-used. Advanced Virgo will form part of a global network of advanced gravitational wave detectors along with Advanced LIGO, GEO HF, and LCGT.
