AC Loss Measurements on NbTi Superconducting Wires for the Vamas Round Robin Test
Abstract A very important parameter of superconducting wires for ac applications is the energy loss dissipated when they are subjected to time-varying magnetic fields1. These losses add to the refrigeration load and in many cases may be the main heat load. Several efforts have been carried out in recent years to obtain superconducting composites suitable for ac applications2,3,4. Their use requires accurate measurements of the ac losses and the establishment of reliable standard techniques for their determination. One of the most effective ways to attain this goal is the use of round-robin tests in which samples from the same lot are measured by several laboratories and the results are correlated. Under VAMAS activity, a cooperative programme has been started for the measurement, with existing techniques and apparatuses, of ac losses on four reference NbTi multifilamentary wires.
