Commissioning status of the Virgo interferometer
The Virgo interferometer is one of the big observatories aimed at detecting gravitational waves. This report will describe the Virgo+ upgrades and the commissioning work performed between the first (VSR1) and the second Virgo Science Run (VSR2). Some first results of VSR2 will be discussed, which was recently started with a good duty cycle and a inspiral range for the detection of binary neutro...
متن کاملActive Controls in Interferometric Detectors of Gravitational Waves: Inertial Damping of the Virgo Superattenuator
The operation of an interferometer for gravitational waves detection requires sophisticated feedback controls in many parts of the apparatus. The aim of this lecture is to introduce the types of problems to be faced in this line of research. The attention is focused on the inertial damping of the test mass suspension of the VIRGO interferometer (the superattenuator): it is a multidimensional lo...
متن کاملThe present status of the VIRGO Central Interferometer*
The VIRGO Central Interferometer (CITF) is a short suspended interferometer operated with the central area elements of the VIRGO detector. The main motivation behind the CITF is to allow the integration and debugging of a large part of the subsystems of VIRGO while the construction of the long arms of the antenna is being completed. This will permit a faster commissioning of the full-size anten...
متن کاملThe Virgo 3 km interferometer for gravitational wave detection
VIRGO, a French-Italian collaboration located in Cascina (Pisa, Italy) aiming at the detection of gravitational waves, is a ground based power recycled Michelson interferometer, which arms are 3-km-long Fabry-Perot suspended cavities. The VIRGO first scientific data taking has started in mid may 2007 in coincidence with the corresponding American detectors. The optical scheme of the interferome...

interferometric gravitational wave detectors must be isolated from seismic noise. The VIRGO vibration isolator, called superattenuator, is fully effective at frequencies above 4 Hz. Nevertheless, the residual motion of the mirror at the mechanical resonant frequencies of the system are too large for the interferometer locking system and must be damped. A multidimensional feedback system, using ...
