Pulsar Contribution to High Energy Cosmic Rays

We show that assuming a simple CR acceleration scenario, where all the pulsar rotational energy is transformed into CR particles of the highest available energy at a given moment, one obtains particle fluxes of the order of the observed ones. The slope of CR energy spectrum for E>1016 eV would be determined by a powerlaw distribution of their initial periods and the spectrum flattening - by the decay of the pulsar magnetic field.
