	The possibility of production of the coils based on high-temperature superconductors (HTS) for accelerator applications is now under preliminary study in many accelerator centres and laboratories. The alternating magnetic field in these magnets causes an energy dissipation (AC losses). The accurate measurement of AC losses is important for a comparison choice among different HTS conductors and for estimations of the total level of losses into final magnet too. This article presents the measurement of transport AC losses (i.e. the losses in magnetic field which is generated by the alternating transport current) in HTS coils. Two model HTS coils with the racetrack geometry have been fabricated from 2nd generation HTS conductor supplied by two vendors.

The possibility of production of the coils based on high-temperature superconductors (HTS) for accelerator applications is now under preliminary study in many accelerator centres and laboratories. The alternating magnetic field in these magnets causes an energy dissipation (AC losses). The accurate measurement of AC losses is important for a comparison choice among different HTS conductors and for estimations of the total level of losses into final magnet too. This article presents the measurement of transport AC losses (i.e. the losses in magnetic field which is generated by the alternating transport current) in HTS coils. Two model HTS coils with the racetrack geometry have been fabricated from 2nd generation HTS conductor supplied by two vendors. The measurement was performed by electrical method at the sinusoidal current with the amplitude up to 32 A and at the frequencies lain into interval from 5 up to 100 Hz. The measurement scheme and results are presented.
