✦ Synopsis

A new high intensity e + e -linear collider serving as tau-charm factory is proposed. The design luminosity is 10 35 cm -2 s -1 for center of mass energies of √ s = 1-5 GeV in the resonance region of Ψ vector mesons and in the region of maximum cross section for tau pair production. This new facility would provide about 10 11 tau lepton pairs per year enabling precision studies of τ leptons and searches for rare τ decays with unprecedented sensitivity.

Implications on the design of the linear accelerator are discussed together with requirements to achieve luminosities of 10 35 cm -2 s -1 or more. The possibility to exploit energy recovery techniques in order to increase e + beam currents and luminosity is discussed.
