Sensitivity of a rigid small interferometer in the 10 Hz frequency region

In the framework of the development of the super attenuators for VIRGO, the French-Italian long arm interferometric antenna for gravitational wave detection, a small interferometer has been built in the Pisa laboratory, to investigate the sensitivity in the low frequency region. The noise measured a...

Summary:In the framework of the development of the super attenuators for VIRGO, the French-Italian long arm interferometric antenna for gravitational wave detection, a small interferometer has been built in the Pisa laboratory, to investigate the sensitivity in the low frequency region. The noise measured at 10 Hz is below 10 −13 m/√Hz, about a factor of 10 less than previous measurements in Munich. Calculation shows that the noise between 10 and 100 Hz is compatible with seismic noise.
