SUPERB SITE OVERVIEW C. Sanelli, F. Sgamma, S. Tomassini, INFN-LNF On behalf of Super. B Collaboration Mini MAC – Frascati – April 23 th 2009

Outline • Super. B at Torvergata: preliminary civil infrastructures design • Super. B at Frascati (LNF+ENEA): preliminary footprint • Conclusions

The Torvergata Site a t a g r e v r o T AREA for the Super. B and SPARX Projects

Roman Villa CNR SPARX & Super. B University Campus Sport City

SPARX 1 st stage Super. B LINAC SPARX future Super. B & SPARX footprint

Site Geology • Formed by the Colli Albani volcano more than 600000 years ago • Very stable volcanic rock S. 1 S. 3 S. 2 S. 5 S. 4 Soil Sea Level Altitude (m) Brown Pyroclastic Rock y r a n i r P m i l e Gray Pyroclastic Rock

Seismic map • http: //zonesismiche. mi. ingv. it/docu menti/mappa_opcm 3519. pdf • Maximum ground acceleration, with a 10% probability of exceeding it in 50 years.

Nanometer Vibrations measurement In order to certificate the site, vibration measurements are foreseen: • on ground surface • underground Few wells will be drilled in the area to do the underground measurement The Pisa INFN VIRGO group (Dr. Braccini and Eng. Gennai) is available to perform these measurements with the help of the Torvergata engineering group and the SPARX team. They have the right expertise and instrumentation. They can do measurements in the range of nanometer. Also the Annecy group (Andrea Jeremie) is interested in this job and has the right expertise and instrumentation. We are waiting for the University authorization

Conclusions • The preliminary feasibility study of the Super. B project on the Torvergata site has been performed. • A preliminary geological survey of the area has given good results on the stability of the site and new tests are foreseen in the building area. • Test to discover archeological ruins are also foreseen and will start as soon as the authorization is given. • Measurements of the environmental vibrations on the ground surface and underground are foreseen and we expect to perform them as soon as the authorization is given. • A very preliminary study to build Super. B complex at LNF-ENEA area has been done. • Geological survey is foreseen at LNF and vibration measurements survey of the area must be organized soon.
