Abstract

Equations are derived here for the dynamics of particles undergoing cyclotron autoresonance acceleration in which elliptically-polarized plane-wave radiation fields are employed. The equations are used to study the acceleration of bare atomic nuclei in astrophysical environments by performing single-particle calculations, supported by many-particle simulations. It is shown that the nuclides 1H1, 2He4, 26Fe56, and 28Ni62, can reach ZeV energies in the presence of superintense radiation and megatesla magnetic fields. Nuclides of any species are shown to attain maximum kinetic energy from interaction with an integer number of phase cycles of left circularly-polarized radiation.
