36 SUMMARY The KSTAR, which is under constructed aiming at the completion on August, 2007, is on the final assembly phase. Also, the KSTAR control system has been developed to integrate many local systems with heterogeneous platforms using EPICS, the first attempt in Fusion device. The KSTAR control system has been developed with expendability for the future long-pulse operation. We have finished successfully the commissioning of TMS, VMS, ECH, and the other systems are planned to commission by August, 2007.
