Notes:
A magnetic gas spring (MGS) has been developed to be the filter element of the super attenuator (SA), the device designed to support the optical components of the gravitational interferometric antenna VIRGO. Measurements have been performed on a MGS in order to study the resonance structure of the attenuation spectra in both the vertical and horizontal directions. Results guarantee an attenuation of at least 40 dB almost everywhere from 10 Hz to 1 kHz. By using experimental data the calculated performances of the SA turn out to be quite adequate for the VIRGO project requirements. © 1995 American Institute of Physics.
