Influence of Coulomb collisions on autoresonant acceleration
Abstract
The acceleration of charged particles to high energies is considered in the field of a plane wave traveling along an external magnetic field in a plasma. Because the particles undergo Coulomb collisions with the dense plasma, the maximum particle energy is limited by the breakdown of the phase synchronism of the particles with the plane wave. However, when acceleration occurs in a vacuum, the particles remain in resonance with the wave as their masses increase relativistically. A system of hydrodynamic equations containing the kinetic gradient is derived from the kinetic equation with a Landau relativistic collision integral, and a solution is found in terms of Fresnel integrals.
