  Main parameters of the linac-ring type charm-tau factory are discussed.
Different sets of parameters for an electron linac and a positron ring have
been considered. It is shown that L=10^33 cm-2 s-1 and even more can be
achieved. The physics goals of this machine in investigation for charmed
particles and tau lepton properties are briefly discussed. Advantages of the
proposed machine in comparison with standard (ring-ring) type charm-tau factory
proposals will be the possibility of the search for rare decays of tau lepton
and charm quark and study of D^0-D^-0 oscillations.
