Design of a High Luminosity Tau/Charm Factory

The design of a high luminosity Tau/Charm Factory has been accomplished by the INFN-LNF Laboratory in Frascati in collaboration with the Consortium Nicola Cabibbo Laboratory. The target luminosity is 10³⁵ cm⁻² ses^{−1} at 4.6 GeV in the center of mass. This design is a natural evolution of the SuperB B-Factory, that was aimed to be built in the Rome Tor Vergata University campus as an Italian Flagship Project. The Tau/Charm design keeps all the features that made SuperB a state-of-the art accelerator, such as the “large Piwinski angle and crab waist sextupoles” collision scheme, the super squeezed beams, and the polarized electron beam. As a plus, it will be possible to collect data at high luminosity in a large energy range (2 to 4.6 GeV c. m.), with a peak luminosity target of 10³⁴ cm⁻² ses^{−1} at 2 GeV. The possibility to extend the Linac for a SASE-FEL facility is also taken into account. A Conceptual Design Report* was published in September 2013. In this paper the design principles and the project features are reviewed.
