โœฆ Synopsis

A technique is described to study the critical current density and penetration field associated with the transport current in a silver sheathed BSCCO conductor. A transport current flowing in a conductor in a varying magnetic field will only influence magnetisation currents that are in competition with the transport current, i.e. currents that use the same path. By measuring the transport current dependence of the magnetisation loss information can be obtained on the related critical current and penetration field. The combination of these two quantities contains information about the geometry of the current distribution and can be used to test different models for the current distribution in BSCCO conductors.

The measurement results of AC transport current losses in BSCCO/Ag tapes caused by AC transport currents and the simultaneously presented AC magnetic fields were reported. The measurements were carried out at 77 K and power frequency (50 Hz) for AC applied magnetic fields of 48, 80 and 120 mT, respe
