The shocked terminations of the relativistic plasma jets emitted by active galactic nuclei (AGNs) have been considered as possible sources of high-energy cosmic rays. However, the acceleration rate provides a stringent limitation on the ability of this class of source to make particles with the highest observed energies. A numerical simulation is reported here of the diffusive shock acceleration process when the flow is relativistic. The acceleration rate is found to be about 13.5-times faster than the previous values used, which were based on an analytical approximation. Significant particle anisotropies appear in the process. This enhancement of acceleration allows even 10 to the 19th-eV protons and 10 to the 20th-eV iron nuclei to be produced in AGNs of the local supercluster.
