The test facility for the KSTAR superconducting magnets at SAIT

SSTF (Samsung Superconductor Test Facility) has been built with the primary goal of testing the KSTAR TF (Toroidal Field) and PF (Poloidal Field) magn ets as well as CICC (Cable-in-Conduit Conductor) and superconducting strand s in the most relevant manner. The facility is located at SAIT (Samsung Adv anced Institute of Technology) near the KSTAR project home site. Two helium liquefiers of 120 liter/hr capacity have been utilized as refrigerators de monstrating simultaneous double mode operation of refrigeration and liquefa ction. A forced flow supercritical helium cooling circuit allows the test f acility to be operated at temperatures down to 4.5 K. Other major SSTF comp onents are a large vacuum vessel (6 m diameter and 7.3 m height) with liqui d nitrogen temperature shield, data acquisition and control system with EPI CS (Experimental Physics and Industrial Control System), current leads, and 50 kA modular power supply with fast dump quench protection circuitry. SST F has been used for the first test-phase of KSTAR CICC sample. The current status of SSTF as the KSTAR magnet test facility for components and qualifi cation test is presented in detail.
