abstract = "Schenberg is a detector of gravitational waves resonant mass type,
with a central frequency of operation of 3200 Hz. Transducers
located on the surface of the resonating sphere, according to a
distribution half-dodecahedron, are used to monitor a strain
amplitude. To improve the performance of the detector it is
essential to decrease the temperature, then it will be cooled
down, this temperature could reach as low as 50 mK. This
refrigerator produces vibration noise that could compromise the
performance of Schenberg detector. In this work we the study such
vibration noise and how it could be minimized proposing a new
connection from the dilution refrigerator to the sphere
suspension. The vibration attenuation is studied by finite element
modeling (FEM) and an attenuation higher than 1024 is found,
higher enough to note compromise the performance of Schenberg
detector.",
