Conclusions

• The feasibility study of the SuperB project on the Torvergata site has been done.

• A preliminary geological study of the area has given excellent results on the stability of the site.

• A strong synergy with the SPARX-FEL project exists, giving the possibility of using the SuperB LINAC as the injector of the fel.
