高温超导带材通流能力Ic是带材应用时的重要性能指标,而不同的环境温度、磁场强度、以及磁场应加角度,都会对Ic产生非常大的影响。为量化测定高温超导带材在复杂磁场,温度环境下的性能,设计了一套可提供4T背景磁场的性能测试装置。该装置可提供0~4T任意角度磁场、20K~77K任意温度环境、0~1000A稳定通流能力的平台。
High-temperature superconducting tape through capacity Ic is an important performance indicators when the strip is applied, and different ambient temperature, magnetic field strength, and the magnetic field should be added to the angle, will have a very large impact on Ic. In order to quantitatively measure the performance of high temperature superconducting tapes under complex magnetic field and temperature conditions, a set of performance testing device that can provide 4T background magnetic field was designed. The device can provide any angle 0 ~ 4T magnetic field, 20K ~ 77K arbitrary temperature environment, 0 ~ 1000A steady flow capacity of the platform.
