要約(日本語): By applying no-insulation winding technique, REBCO coils wound with ‘defect’ tapes barely show discernible electromagnetic behaviors from their defect-free counterparts in experiments. This makes it possible to build a REBCO pancake coil using commercial REBCO tapes, and reduce the cost. In this study, an analysis based on PEEC model coupled with thermal simulation is conducted, for a 60-turn REBCO pancake coil, whose Ic in the middle of the tape is set to be 25% of its original value, as a ‘defect’. According to the result, it is confirmed that the ‘defect’ coil can almost generate desired magnetic field, and the reason is also clarified.
