Study of Plasma Current Density and Q-profiles for Circular Cross Section Tokamak

In this paper the current density J(r) and safety factor q(r), profiles are obtained for circular cross section HT-7 tokomak. For this purpose discrete poloidal magnetic probes along with the diamagnetic loop can be utilized for the measurement. Here Plasma internal inductance is studied by theoretical and experimental approach for circular cross section HT-7 Tokamak plasmas. Moreover, a few approximate values of the internal inductance for the different possible profiles of the plasma current density are also calculated. From the results, current density and q-profiles are obtained.
