The vast bulk of cosmic-ray (CR) nuclei and electrons are thought to be accelerated in the shock waves of SNRs. The location of strong shocks and more extended structures than SNRs can potentially accelerate particles above 100 TeV. The Chandra X-ray Observatory has now resolved the X-ray spatial structure along jets, from kpc to Mpc, of more than a dozen of radio galaxies. These observations have established that particles are accelerated efficiently in radio galaxies, up to energies of 10-100 TeV. I present recent progress in the Chandra observation of AGN jets and discuss the energy transport from the vicinity of the central black hole to the kpc scale jets.
