• by specifically being in charge for the last stage of the suspension system of the VIRGO mirrors
The improvement of the thermal noise
limit is still a scientific target pursued
during the construction of the detector
payloads of the upgrade version of
VIRGO, and it is a main issue of the
design study of ET, the GW detector of
third generation, a project financed by
the European Union in the context of
the Framework Program 7.
1.2.4 Cosmic Rays
The last frontier for cosmic rays studies
resides in UHE Neutrino detection. It
will complement the one performed
with muons, photons and primary
hadrons. A Roma group [P31, P32]
is participating both to ANTARES
and NEMO with the final goal of an
experiment of 1 km 3 to be performed in
the Mediterranean sea. The group has

participated actively in the characterization of deep-sea sites and has developed the electronics
for such experiments. The project is partially financed by UE through the KM3NeT consortium.
