Abstract
Magnetic diagnostics is one of basic measurement systems for Tokamak plasma current and shape control. The accuracy of magnetic data will influence the plasma shape reconstruction. In this paper, the calibration of magnetic diagnostics is carried out on the EAST Tokamak. The overall uncertainties of magnetic sensors are analyzed from the calibration and vacuum shots. The uncertainty results are used as fitting weight in plasma shape reconstruction code (EFIT). Based on EFIT simulation and experiment data fitting results, the sensitivity of the magnetic data uncertainty in the plasma shape reconstruction is analyzed.
