Development of Numerical Model of KSTAR PF Conductor and Magnet for the Analyses of AC Loss on the Results of KSTAR PF Magnet Test Run

To analyse the experimental results of PF magnet during the commissioning test of KSTAR, a numerical model of the PF1 magnet and its CICC was developed for the evaluation of Joule heat from the AC loss due to the time varying field profile along the conductor during ramping-up or down taking into account the ferromagnetic effect of Incoloy 908 jacket. The calculation routines was carefully updated to make a proper estimation of the AC loss and applied to the estimation of AC loss parameters of the CICC of the KSTAR PF magnet.
