Abstract:
The method of plasma current profile reconstruction using the polarime- ter/interferometer (POINT) data from a simulated equilibrium is explored and validated. It is shown that the safety factor (
q) profile can be generally reconstructed from the external magnetic and POINT data. The reconstructed q profile is found to reasonably agree with the initial equilibriums. Comparisons of reconstructed q and density profiles using the magnetic data and the POINT data with 3%, 5% and 10% random errors are investigated. The result shows that the POINT data could be used to a reasonably accurate determination of the
q profile.
