Test Results of the DPC-TJ-Electromagnetic Performance

The DPC-TJ coil experiment took place successfully at the Japan Atomic Energy Research Institute (JAERI) in 1991. This coil was developed by Toshiba and JAERI in collaboration to demonstrate the realizability of superconducting coils for fusion with high average current density of 40A/mm2. The DPC-TJ was charged up to its rated current of 24kA (40A/mm2) at 7.6T without quench in the DPC test facility. Thereafter the electromagnetic performances were tested by measuring Ic and Tcs, and the critical current at 12T was estimated 41kA. Many electromagnetic results were obtained, which are necessary for the design of the next fusion machines like International Thermonuclear Experimental Reactor (ITER).
