Abstract.  The KSTAR is aiming at the successful preformance of the advanced tokamak (AT) mode of operation as well as the steady state operation with fully superconducting magnets. To support the current density and pressure profile control experiments for AT operations, development activities are being concentrated on the profile diagnostics such as the motional Stark effect (MSE) polarimetry, the Faraday Rotation polarimetry and densiometry, interferometry, and reflectometry. Even for active feedback control of the MHD unstable states of plasmas, extensive sets of magnetic diagnostics are being prepared and tested. The edge and divertor areas are also going to be actively diagnosed to understand the multiply-coupled characteristics with the AT operations. The present status and activities for the development of the KSTAR diagnostics will be described with test results obtained by utilizing HANBIT mirror plasmas.
