Abstract
We calculate energy spectra and mass composition of cosmic rays accelerated by the galactic population of pulsars during their radio and gamma-ray phase. Several models proposed for the distribution of the initial parameters of the galactic pulsar population are considered. The best description of the observed cosmic ray spectrum and mass composition between 10^15 eV and 10^18 eV is obtained for the model B of Lorimer et al. (1993) in which the logs of initial pulsar periods and surface magnetic fields are given by the Gaussian distributions with the average values of log P[ms] = 2.6 and log B[G] = 12.3, respectively.
