More than a century after the discovery of superconductors (SCs), numerous studies have been accomplished to take the advantage of SCs in physics, power engineering, quantum computing, electronics, communications, aviation, health care, and defence-related applications. However, there are still challenges that hinder the full-scale commercialization of SCs, such as the high cost of superconducting wires/tapes, technical issues related to AC losses, the structure of superconducting devices, the complexity and high cost of the cooling systems, the critical temperature, and manufacturing related issues. In the current century, massive advancements have been achieved on artificial intelligence (AI) techniques by offering disruptive solutions to handle engineering problems. Consequently, AI techniques can be implemented to tackle those challenges facing superconductivity and act as a shortcut towards full commercialization of SCs and their applications. AI approaches are capable of providing fast, efficient, and accurate solutions for the technical, manufacturing, and economic problems with a high level of complexity and nonlinearity in the field of superconductivity. In this paper, concept of AI and the widely used algorithms are first given. Then a critical topical review is presented for those conducted studies that used AI methods for improvement, design, condition monitoring, fault detection and location of superconducting apparatuses in large scale power applications, as well as the prediction of critical temperature and the structure of new SCs, and any other related applications. The topical review are presented in three main categories, AI for large-scale superconducting applications, AI for superconducting materials, and AI for physics of superconductors. In addition, the challenges to apply AI techniques to the superconductivity and its applications are given. Eventually, future trends on how to integrate AI techniques with superconductivity towards the commercialization are discussed.

In order to design high temperature superconducting (HTS) Maglev launch system, three NdFeB permanent magnetic guideways (PMGs) are investigated and compared for the better levitation forces and guidance forces. The laboratory-scale HTS Maglev launch system was designed and developed successfully in the Applied Superconductivity Laboratory (ASCLab), Southwest Jiaotong University, China. The cooling process of the melt-textured YBaCuO bulk superconductors is made in a big low temperature tube, which is connected with PMG. The method merit is to eliminate fluctuation of liquid nitrogen in the operation test. The longitudinal slopes of the PM guideway are designed with 0-30 degree from the horizontal, and transverse slopes is designed with 15 degree from the horizontal. The HTS Maglev launch system is carried out an experiment in the laboratory. Test results indicate design validity of the HTS Maglev launch system. Index Terms-High temperature superconductors, launch, levitation force, Maglev, vehicle.

“…The high-T c superconducting (HTS) bulk can stably levitate above permanent magnet (PM) without any complex controlling system. Based on the inherent stability characteristics, HTS bulk has more potential applications in many fields, especially in HTS maglev vehicle [1][2][3][4]. Recently years the new superconductor's theory and materials technology development (such as Fe-based superconductor) may enhance the HTS potential for various engineering applications [5].…”

The magnetic levitation transportation system is one of the potential applications of high-T_c superconducting (HTS) maglev system. The prototype HTS magnetic levitation system is composed of one HTS bulk and a permanent magnet railway (PMR). The maglev transportation system performance is influenced by the maximum levitation force, the maximum guidance force and the maximum of external applied magnetic flux density. The applied magnetic field distribution also needs to be considered carefully. In the paper, the magnetic levitation force of cylindrical HTS bulk over PMR is experimentally studied. During the experiment, symmetrical PMR and Halbach PMR are used separately. The levitation force-gap loops of different lateral offset of the HTS bulk above PMRs are obtained experimentally. The results show that the HTS bulk levitation performance is tightly relative to the external applied magnetic field distribution. The maximum magnetic levitation forces of HTS bulk above symmetrical PMR decrease linearly with the lateral offset increasing. When the lateral offset changes from 0 mm to 25 mm, the maximum magnetic levitation forces of HTS bulk above Halbach PMR increase with the lateral offset increasing. When the lateral offset exceeds the center of the Halbach PMR by 25 mm, the maximum force decreases rapidly with the increase of the lateral offset of the bulk sample.
