Description
The direct detection of the first Gravitational Waves signals by using a ground based laser interferometric network, put in evidence the importance of having a filtering system of seismic noise and local disturbances integrated into the experimental apparatus. The third generation detectors will have more stringent requirements, in terms of sensitivity, and the new instrument should be equipped with a suspension system able to better reduce the transmission of seismic noise to the optical components all over the detection bandwidth. In this presentation, I will focus my attention on a few peculiarities to be used as guidelines in the project of a New Generation of Superattenuators (NGSA) to be installed in an Underground Laboratory with the payload at cryogenic temperature and also with the intent to extend the detection bandwidth in the low frequency region (below 3 Hz).
