Abstract
The French-Italian collaboration VIRGO is presently building an interferometric gravitational wave detector aimed at measuring spectral strains in Vacuo as small as 10-23/√Hz in the bandwidth 5 - 104Hz. Elimination of thermal noise effects poses new challenges to internal friction experts. VIRGO requirements and strategies are outlined here with the purpose of stimulating discussion, advice and, possibly, collaboration.
