Abstract

In this work we present the plasma displacement and ß_p +l_i/2 by the Simplest Grad-Shafranov Equation (GSE) solution using Solov'ev assumption for circular cross section HT-7 tokamak. Using diamagnetic and compensation loop, combining with poloidal magnetic probe array signals, plasma displacement and ß_p +l_i/2 are measured. In this paper, theoretical and experimental results in determining plasma displacement and ß_p +l_i/2 are presented. We have seen that the calculated plasma displacement and the calculated ß_p +l_i/2 depend on the kind of discharge or plasma current.

Keywords: Magnetohydrodynamics; two-fluid and multi-fluid plasmas.
