Abstract
In this work, we present the poloidal beta βp and internal inductance li by solving the simplest Grad—Shafranov equation (GSE), using the Solov'ev assumption for an HT–7 tokamak with a circular cross section. The poloidal beta and internal inductance are measured by using diamagnetic and compensation loops, combined with poloidal magnetic probe array signals. In this paper, theoretical and experimental results of determining βp and li are presented. The calculated poloidal beta and internal inductance are demonstrated to depend on the kind of the discharge or plasma current.
