The Virgo gravitational wave detector is an interferometer with 3 km long arms in construction near Pisa to be commissioned in the year 2000. Virgo has been designed to achieve a strain sensitivity (SNR D 1) of a few times 10−23 Hz−1=2 at 200 Hz. A large effort has gone into the conception of the mirror suspension system, which is expected to reduce noise to the level of 10−21 Hz−1=2 at 10 Hz. The expected signals and main sources of noise are briefly discussed; the choices made are illustrated together with the present status of the experiment.

Abstract
The Virgo gravitational wave detector is an interferometer with 3 km long arms in construction near Pisa to be commissioned in the year 2000. Virgo has been designed to achieve a strain sensitivity (SNR D 1) of a few times 10−23 Hz−1=2 at 200 Hz. A large effort has gone into the conception of the mirror suspension system, which is expected to reduce noise to the level of 10−21 Hz−1=2 at 10 Hz. The expected signals and main sources of noise are briefly discussed; the choices made are illustrated together with the present status of the experiment.File in questo prodotto:
