15. Feasibility study for ET Infrastructure for Sardinia site: location optimization, GIS-BIM three-dimensional modelling, multicriteria analysis

Prof. Maria Marsella

09/11/2021, 09:00

Talk

The talk describes the feasibility study activities related to the selection of the optimal configuration and localization of the ET infrastructures in Sardinia. This analysis requires the simultaneous evaluation of several scientific, territorial, environmental and geological/geotechnical aspects. For this reason, a different specific tools, interconnected with each other, have been...

14. Main geotechnical issues and planned investigations for the design of ET Infrastructure in Sardinia

Mr Claudio Rossini

Talk

An overall feasibility study is carried out in Sardinia as one of potential site for the construction of the Einstein Telescope (ET). One of the primary activities of this feasibility study is the design and implementation of a geotechnical and geophysical campaign aimed to acquire all the information for the development of an accurate geo-mechanical model of the rock masses which will host...

38. The Center for Astrophysics in Lusatia - a possible ET site?

16. Geotechnical Characterization Campaign for Design of ET Underground Infrastructures - Tunnelling Aspects and Challenges

Pooya Hamdi (Senior Scientist, RWTH University Aachen)

Talk

The Einstein Telescope (ET) is an advanced gravitational-wave observatory, currently in the planning stage that allows to further understanding the Universe through the observation of gravitational waves. The border region between the Netherlands, Belgium and Germany (Euregio Meuse-Rhine) is being considered as a possible location to host the third generation gravitational wave observatory due...

13. Design and construction of two boreholes for seismometers installation in support of ET seismic characterization in Sardinia

Mr Claudio Rossini

09/11/2021, 11:30

Talk

One of the key activities in the context of seismic and environmental noise characterization has been the installation of two borehole seismometers in proximity of potential ET triangle corners. The design has been completed in July 2020, the boreholes excavation with relevant surface works between April and August 2021 and the sensors installation in September 2021.
The measurement station...

28. Ground Tilt

Enrico Calloni (Istituto Nazionale di Fisica Nucleare)

09/11/2021, 12:00

Talk

The coupling of ground tilt with the longitudinal degree of freedom is
addressed, both in low frequency, below 100 mHz, and the the new frequency
region addressed by ET, namely above 2 Hz.
It is shown, at the present stage of ET design, the need of a strong
interaction with suspension design WPs, in order to recover the site
conditions needed for the planned ET sensitivity.
