Abstract

An interferometric sapphire transducer has been used to test the super attenuator of the VIRGO laser interferometer gravitational wave antenna project. A test was carried out to characterise the horizontal displacement of the attenuator. The test showed the performance of the super attenuator to the transducer noise floor of 5 x 10(-15) m/square-root Hz at 60 Hz.
