摘要：

The interruption of a filament in filamentary YBCO conductors reduces the critical current of the tape along the whole length of the tape Multiply connected filamentary YBCO superconducting tapes were previously proposed as a means to allow current sharing between filaments in case of such interruption. To study the efficiency of such architecture, we studied the I-V curves and critical currents of model filamentary YBCO tapes with 10 filaments 1 mm wide, which were interconnected by several superconducting bridges. The effect of a break in one or more filaments on the I-V curves, n-factor, and critical current of the model tape was measured and reported. The effect of the contact arrangements on the current distribution in the filaments of the tape was also studied.
