Determination of Plasma Position using Poloidal Flux Loops and Comparing with Analytical Solution in IR-T1 Tokamak

In this contribution we presented comparative measurements of tokamak plasma position. In the first technique, two poloidal flux loop were designed and installed on outer surface of the IR-T1 tokamak chamber, and then the plasma displacement obtained from them. To compare the result obtained using this method analytical solution of the Grad-Shafranov equation based on expansion of free functions as quadratic in flux function is also experimented on IR-T1. Results of the two methods are in good agreement with each other.
