In the first cycle of experiments new precision measurements of J/psi- and psi'-meson masses were performed using the resonant depolarization method for the beam energy calibration. As a result of the measurements, the masses of these narrow resonanses, serving the base of the psi-family spectroscopy, were measured with an accuracy 3 times better as compared to the world average. In the new cycle of experiments, which was begun in 2004, we plan to continue study of physics of psi-mesons, and also to carry out a precision measurement of the tau-lepton mass.
