摘要：

The AC losses in a high-temperature superconducting (HTS) tape were measured calorimetrically in longitudinal magnetic fields while carrying transport currents. The experimental data were compared to relevant loss equations based on the critical state model. Also, with no transport current, the longitudinal losses were compared to losses due to perpendicular and parallel magnetic fields. At high magnetic fields the AC losses in longitudinal fields were one-third of those in parallel field. These relatively low losses make the HTS tapes available today competitive to conventional conductors in special applications where the conductor is exposed to longitudinal magnetic fields.
