Abstract

Measurements atT=4.2 K of the mechanical-transfer function (m.t.f.) and of the Brownian noise of a small test antenna using a new type of suspensions are reported. These suspensions operate as a double mechanical filter and their m.t.f. has been measured in order to investigate their use for the big (5 t) gravitational-wave antenna now being assembled at CERN by the Rome group. The experimental results are in good agreement with the expected values.
