VIRGO R&D

Collaboration:

Laboratory: Collaboration sites

National Responsible: F. Vetrano (Urbino/Fi)

1. Goal of the experiment

Virgo R&D is an experiment constituted by many sub-projects aiming at insuring that projected sensitivity of Virgo detector (the gravitational antenna which has been built in Cascina, near Pisa) will be reached and preserved, or else to improve Virgo sensitivity by reducing the noise. From this point of view, Virgo R&D is presently the most powerful effort to improve the performances of ground-based interferometric gravitational detectors at short- and medium –time.
