SPARX 1 st stage SuperB LINAC SPARX future SuperB & SPARX footprint Preliminary SuperB footprint decided last year with the University of Torvergata. A new more precise design is coming. The Torvergata engineering group is working on it. We had a delay of one month due to the change in the University head and the nomination of the new responsible of the civil infrastructures of the area.

Nanometer Vibrations measurement In order to certificate the site, vibration measurements in situ 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

SPARX future

Conclusions The preliminary feasibility study of the SuperB project on the Torvergata site has been performed. A preliminary geological study 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 by the end of March in collaboration with SPARX. A precise design of the Campus area (from a urban point of view) is underway, we had a delay of almost one month due to the nomination of the new head at the University. A strong synergy with the SPARX-FEL project exists, there is the possibility to use the SuperB LINAC as the “injector” of the fel for future upgrade.
