Investigation of particle and energy transport in the edge region of IR-T1 tokamak

Abstract

For a comprehensive understanding of the mechanism of tokamak transport phenomena, both energy and particle transport must be considered in fusion plasma. In this approach, plasma transport in the edge region of IR-T1 tokamak is investigated by analyzing the measured experimental data and discussed. Here, the transport neoclassical equations are used since they are in consistent with geometrical fitures of the torus. The measured results, such as time evaluation of particle density, induced particle flux and thermal flux in the deuterium plasma are utilized to determine the transport coefficients. To this aim the particle and energy conservation equations and diffusion equation are employed. Time evaluation and radial profiles of diffusivity and thermal conductivity for IR-T1 tokamak are obtained and compared. By using of kinetic equation and Fokker-Planck equation, and poloidal component of plasma rotation speed, the Maxwell distribution function is plotted for IR-T1. Also some statistical properties of plasma such as Probability Distribution Function are investigated.
