摘　　要：The method of plasma current profile reconstruction using the polarimeter/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.The method of plasma current profile reconstruction using the polarimeter/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.
