Abstract

Within a model that includes a plasma, a vacuum gap and a wall of the tokamak chamber, the conversion of a plasma current poloidal magnetic field into the kinetic energy of runaway electrons (REs) in the termination phase of the discharge disruption is investigated. The equation for the change in the kinetic energy of REs is obtained, that allows to determine the change in the specified energy in the general case with the known REs density profile, REs current density and the magnetic field. For a flat plasma current density profile, an upper estimate for the REs kinetic energy and conversion was obtained.
