Abstract

The effect of magnetic barrier which is produced by the local modification of safety profile on confinement time of chaotic magnetic fields in tokamak is studied. Magnetic divertor coils are used to enhance plasma confinement and to remove some plasma instabilities in tokamak. Producing chaotic fields near the plasma edge, on the other hand decreases plasma confinement time by increasing radial transport. So magnetic barriers are used in plasma edge to increase confinement time by limiting or reducing radial diffusion of chaotic field lines.
