Paper Abstract

The possibility of creating magnetic configurations with improved confinement based on the laser ablation of a pellet of frozen hydrogen is considered. The advantageous characteristic of the proposed laser methods is that they allow a local control of the plasma parameters and magnetic field. To solve the above problems, a frozen-hydrogen pellet is injected into the plasma volume and irradiated by laser pulse. As a result of mutual diffusion of laser plasma and magnetic field, some profiles of plasma density and magnetic configuration are realized. It is shown that quasi- stationary equilibrium states of tokamak plasma column sustained by the uninterrupted fuel feeding ca be constructed. It is found that specified profiles of plasma density and magnetic field can be provided by using some plasma particles source whose intensity is determined by the laser flux density.
