A multi-channel Thomson scattering system viewing the edge and core of the KSTAR plasma will be installed at the midplane port Bay-N. An engineering design study was undertaken at PPPL in collaboration with the Korea Basic Science Institute (KB Si to determine the optimal optics and cassette design. Design criteria included environmental, mechanical and optical factors. All of the optical design options have common design features; the Thomson scattering laser, an in-vacuum shutter, a quartz heat shield and primary vacuum window, a set of optical elements and a fiber optic bundle. Neutron radiation damage was a major factor in the choice of competing lens-based and mirror-based optical designs. Both the mirror based design and the lens design are constrained by physical limits of the Bay-N cassette and interference with the Bay-N micro-wave launcher. The cassette will contain the optics and a rail system for maintenance of the optics

Korean ITER participation impacts huge things on her fusion research as an energy development program. The ITER Transitional Arrangements (ITA) is conducted by the International Team with supports from participant teams. The Korean participant team (KO-PT) has contributed to the ITA by sharing several technical tasks to verify feasibilities of fabrication and quality control method in procuring ITER equipments and facilities. Technical data to confirm validity of the present design have also been developed on some issues. Completing these technical preparations will make it possible to finalize the specification of ITER procurements. This presentation provides an overview focusing on critical activities needed for the successes of ITER project and fusion energy development
