Abstract

In this paper we present two methods for determination of plasma position in IR-T1 tokamak: a multipole moments method and analytical solution of equilibrium problem or Grad–Shafranov equation. In the multipole moments method a modified rogowski and saddle coils were designed, constructed, and installed on outer surface of IR-T1 tokamak chamber, then displacement of plasma column were measured from them. To compare the plasma position obtained using this method, analytical solution of Grad–Shafranov equation is also demonstrated on IR-T1 tokamak. Results are in good agreement with each other.
