First performance test of the 12 T split coil test facility SULTAN III

The test facility SULTAN III at PSI is primarily devoted to qualification of full-size conductors developed for the next generation of fusion experimental devices. Very recently, the facility generating magnetic fields in excess of 11 T was completed and successfully tested. The split coil arrangement with a radial access of 94 mm*144 mm is ready to perform tests of superconductors carrying currents up to 50 kA at temperatures between 4.5 K and 7 K. First results on a fusion dedicated prototype conductor are presented. The main features of the SULTAN III facility are summarized.>
