KSTAR 초전도 자석의 운전 안정성에 대한 연구
Study of Energy Margin and Operating Current Margin of KSTAR Cable-In-Conduit Conductor
초록
Since the margins for the minimum quench energy and for the operating current in the superconducting magnet determine the operating regime of the magnet, a thermal stability analysis for the KSTAR superconducting magnet system is performed using 1-D Gandalf code. The result shows that the minimum quench energy is about 500 mJ/cc and the operating current margin is about 70 %. These values are larger than those of the KSTAR design criteria and the KSTAR superconducting magnet system can be operated stably under various experimental environments.
