Abstract

This paper describes and HTS tape(s) to be tested which is wound in a bifilar winding arrangement and which allows determination of the current-voltage curve or Ic over long lengths of HTS tape in a compact geometry and with low Ic suppression due to magnetic field effects. Current flow in a first tape is used to cancel the magnetic field effect of a second tape so that accurate current measurements may be obtained, even in a tightly wound spiral geometry.
