- Abstract
The model comprising a plasma column, a vacuum gap, and the wall of the tokamak chamber is used to investigate the process of converting the energy of the poloidal magnetic field generated by plasma current into the kinetic energy of the runaway electrons (RE) in the termination phase of the discharge disruption. The equation for the change in the kinetic energy of RE is obtained, which makes it possible to determine the change in energy specified according to known profiles of RE density, RE current density, and the magnetic field in the general case. The maximum estimate is obtained for the energy and for the conversion rate for a flat plasma current density profile.
