The high-temperature superconductors are being increasingly employed to construct electromagnets to generate strong magnetic field for a broad range of applications: from medical devices, electric motors, to future fusion reactors. These superconductors can experience a quench phenomenon which manifests itself as a fast increase of temperature i…
The application of dc magnetic field to a 2G high temperature superconducting (HTS) tape can reduce the critical current Ic of the tape, without driving the material normal. This property can be used in the development of HTS switching elements through so-called Jc(B) switching. The design of a dc magnetic field switch is reported, in both singl…
