Abstract
In this contribution we have measured the horizontal displacement of the plasma column center using two analytical solutions of the Grad–Shafranov equation in the IR-T1 tokamak. In the first technique, four magnetic pickup coils were designed, constructed and installed on the outer surface of the IR-T1 tokamak chamber and then plasma displacement was determined from them. To compare the results obtained using this method, the second analytical solution of the Grad–Shafranov equation based on expansion of free functions as quadratic in the flux function is also experimented on in the IR-T1. The results of the two methods were compared and were found to be in good agreement with each other.
