Optimization of Pulsed Current Profile for Magnetic Field Trapping in High TC Superconductors
Compared with conventional field-cooling and zero- field cooling magnetization methods, pulsed field magnetization is an alternative way to magnetize high temperature superconductors (HTS) with the advantage of dramatically decreasing the size and complexity of the electromagnetic system. Experiments were carried out with a flexible pulsed-current generator. A series of three pulses was found to be adequate to magnetize the HTS monolith with optimal trapped field if proper pulse amplitudes and widths are applied. The effects of the amplitude, width, ramp rate, and shape of the pulsed current are reported. Transient responses of the HTS to pulsed magnetic fields are discussed and analyzed.
