STUDY OF PLASMA POSITION BY THE ANALYTICAL SOLUTION OF GRAD–SHAFRANOV EQUATION FOR HT-7 TOKAMAK

Abstract

In this work, we present approximation of plasma position by two methods on HT-7 Tokamak. In the first method, solution of Grad–Shafranov equation are presented and one relation for plasma position is obtained. A generalized Grad–Shafranov-type equation has been used. Specific functional forms of plasma internal energy and current are used. In second method, according to magnetic fields distribution around the plasma, second relation for plasma position is obtained. Plasma position is obtained by magnetic probes. Results of the two methods are in good agreement with each other.
