Abstract
The KSTAR (Korea Superconducting Tokamak Advanced Research) pursued to develop key technologies for superconducting tokamak operation and to contribute to a few research items for ITER relevant issues. As a result, the KSTAR achieved highly confined mode (Hmode) in 2010 campaign and successfully demonstrated suppression of Edge Localized Mode (ELM) using n=l Resonant Magnetic Perturbation (RMP) coils. The KSTAR is also initiating machine performance based on the designed machine parameters. The plasma current we achieved was I MA, and longest plasma pulse length has been extended to 10 s. In spite of limited heating power to 3.5 MW, several key actuators satisfactorily supported to implement a few scientific researches such as ELM control. On the basis of big progress in both the plasma performance and the experimental results, the KSTAR operation will explore key scientific and technical research issues under steady state operation condition in phase-2 operation.
