AC loss measurements—Magnetometer methods for hysteresis loss in Cu/Nb-Ti multifilamentary composites

IDT  IEC 61788-13:2003

全国超导标准化技术委员会

本标准描述了运用直流或低扫场速率磁强计方法对Cu/NbTi多丝复合线磁滞损耗进行测量的相关事宜。本标准所针对的是Cu/NbTi多丝复合导体中磁滞损耗的测量。测量应在4.2 K或4.2 K附近的温度下针对圆形线进行。直流或低扫场速率磁强计法使用的是超导量子干涉器件(SQUID)磁强计或振动样品磁强计(VSM)。如果测量中发现用不同的(但均校准过的)磁强计所得的结果存在差异,则以VSM在外推至零扫场速率下测量的结果为准。
