An Induction Accelerator of Cosmic Rays on the Axis of an Accretion Disk

Abstract

The structure and magnitude of the electric field created by a rotating accretion disk with a poloidal magnetic field is found for the case of a vacuum approximation along the axis. The accretion disk is modeled as a torus filled with plasma and the frozen-in magnetic field. The dimensions and location of the maximum electric field are found, as well as the energy of the accelerated particles. The gravitational field is assumed to be weak.
