本文对两种类型的2G高温超导赛道线圈的交流磁化损耗进行了比较研究。由Rabits制造的磁性衬底是这两种类型的主要区别，因为由磁性衬底引起的铁磁损耗被计入总交流损耗。IBAD和Rabits胶带被成功地缠绕成具有相同几何形状的赛道形状。测量采用电磁法，在77K的外加正弦变化的磁场中，幅度可达27mT，范围为10~100 Hz，磁场方向垂直于磁带表面。应用理论模型对实验测量结果进行了验证，结果表明，由于磁性衬底的存在，MAG Rabits线圈中的磁化损耗始终高于非MAG线圈中的磁化损耗，从而增加了磁场对线圈的穿透，导致穿透区域内的磁场密度较高。
This paper presents a comparative study of ac magnetization losses in two types of 2 G HTS racetrack coils. The magnetic substrate made by RABiTS is the main difference between the two types, because ferromagnetic loss caused by magnetic substrate is accounted into the total ac losses. IBAD and RABiTS tapes were successfully wound into racetrack shape with identical geometry. The measurements were carried out by using electromagnetic method with pick-up coils under a sinusoidally varying external magnetic field, with amplitudes up to 27 mT, ranging from 10 Hz to 100 Hz at a temperature of 77 K. The field was oriented perpendicularly to the surface of the tapes. Experimental measurements were validated by applying theoretical models and the results showed that the magnetization loss in the MAG RABiTS coil is always higher than that in the NON MAG coil due to the presence of the magnetic substrate, which increases the magnetic field penetration into the coil and causes higher magnetic flux density within the penetrated region.
