This patent concerns a collective particle accelerator including an intense relativistic electron beam IREB generator, an automodulation section, an acceleration region and injection region. A negative high voltage is applied to a ring cathode which produces an IREB. The IREB propagates through the accelerator. On propagating through the automodulation section, the electrons are modulated thereby forming them into ring-shaped bunches. The acceleration section is surrounded by a longitudinal uniform magnetic field along its length and is provided with special magnetic field means which changes the uniform magnetic field to a rippled magnetic field. The rippled magnetic field causes the bunches of electrons to contract and expand radially as they propagate through the rippled magnetic field which in turn causes ions or electrons injected into the system to be accelerated by attraction or repulsion as the electron rings contract and expand radially.
