Abstract
The radial Shafranov shift (ΔR) and vertical shift (ΔZ) has been calculated for steady state superconducting tokamak (SST-1) experimentally using magnetic probes and flux loops. The SST-1 plasma at the present phases of operations is circular in shape and leans against the limiters. The radial and vertical shift formulated from Shafranov equation have been used for computation. We have selected best possible pairs of flux loops and magnetic probes location for the measurements. The comparison of results obtained from these two methods also has been performed for numerous numbers of shots for repeatability and reliability purpose. We have observed that the results of both the methods are in good agreement for almost all SST-1 experiment campaigns. Since the control of plasma position plays an important role in plasma confinement and optimizing tokamak operations, the computed ΔR and ΔZ could later on be used as a control parameter for feedback control of plasma position in SST-1.
