Design of a High Luminosity Tau/Charm Factory

Abstract

The design of the SuperB B -Factory [1] has been inspiration for several other proposals and is the base of the SuperKEKB new design. SuperB was a state-of-the art accelerator for which new ideas were developed, such as the “Large Piwinski Angle and Crab Waist Sextupoles” (LPA&CW) collision scheme, super-squeezed beams, and polarized electron beam. The same design criteria were applied to a high luminosity Tau/Charm Factory designed by the INFN-LNF Laboratory in Frascati in collaboration with the Consortium Nicola Cabibbo Laboratory. The target luminosity is 10 35 cm -2 sec -1 at 4.6 GeV in the center of mass. The possibility to extend the Linac for a SASE-FEL facility was also taken into account. A Conceptual Design Report [2 ] was published in September 2013. Since the design of an intermediate energy e + e collider with high peak luminosity is still of interest for many laboratories worldwide, in this paper the design principles and the project features are summarized.
