Abstract

I discuss a proposal for a high intensity $e^+e^-$ linear collider operated at low center of mass energies $\sqrt{s}<5$ GeV with high intensity beams. Such a facility would provide high statistics samples of (charmed) vector mesons and would permit searches for LFV with unprecedented precision in decays of $\tau$ leptons and mesons. 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.
