“…H-formulation, namely, is the mathematical model with the dependent variable of the magnetic field intensity H, which was first applied to the study of superconductivity in 2003 [21]. H-formulation generally consists of Maxwell Ampere's Law (1), Faraday's Law (2), Constitutive Law (3), Ohm's Law (4) and E-J power Law (5):…”

“…In recent years, the electromagnetic performance of HTS has enhanced, while the price of HTS has been gradually decreasing [3]. All these advantages make HTS technically and economically possible for future superconducting power applications, such as HTS high-field magnets [4], HTS motors/generators [5,6], HTS transformers [7,8], HTS power transmission cables [9], HTS fault current limiters [10].…”

This paper overviews the computation of the alternating current (AC) loss in high temperature superconductors (HTS) based on the finite-element method (FEM) using H-Formulation. A great amount of studies shows that the AC loss calculation results from H-Formulation agree well with the experiment results. As one of the most reliable numerical modeling methods, H-Formulation is able to calculate the AC loss from a wide range of HTS topologies. In this paper, we review these contributions on the AC loss calculation using H-Formulation, from small-scale HTS tapes and coils, HTS cables, to large-scale HTS applications.

“…Second, pre-existing cracks in the REBCO layer from the tape-slit process can induce further degradation under the large hoop tension due to Lorentz load [18,143]. For solenoid insert coils wound with single tapes, one may avoid this issue by properly orienting the slit edge with respect to the background solenoid fields [18]. For magnets based on multi-tape REBCO conductors featuring more complex conductor and magnetic field orientations, more fundamental solutions are needed to eliminate the crack formation during the tape fabrication process.…”

“…Measurements based on the scanning Hall probe can give valuable insight on the spatial distribution of the critical current density that can help explain the source of the observed critical-current fluctuation [198][199][200][201]. In particular, the Hall probe measurements effectively reveal the damage pattern and identify the causes of conductor damage that occurred in the REBCO pancake coils achieving the record 45.5 T dc field [18]. A similar method has been successfully applied to individual strands of Roebel cables, identifying the sources of I c reduction [202].…”

“…Although the anticipated utility applications have not yet been realized, high-field magnet applications have been rising as an important customer for the REBCO market [12][13][14]. An early and strong ongoing direction is the solenoid magnet applications based on single REBCO tapes that lead to a series of record dc magnetic fields with the most recent one reaching 45.5 T [15][16][17][18].…”

Dipole Magnets above 20 Tesla: Research Needs for a Path via High-Temperature Superconducting REBCO Conductors

2019

To enable the physics research that continues to deepen our understanding of the Universe, future circular colliders will require a critical and unique instrument—magnets that can generate a dipole field of 20 T and above. However, today’s maturing magnet technology for low-temperature superconductors (Nb-Ti and Nb 3 Sn) can lead to a maximum dipole field of around 16 T. High-temperature superconductors such as REBCO can, in principle, generate higher dipole fields but significant challenges exist for both conductor and magnet technology. To address these challenges, several critical research needs, including direct needs on instrumentation and measurements, are identified to push for the maximum dipole fields a REBCO accelerator magnet can generate. We discuss the research needs by reviewing the current results and outlining the perspectives for future technology development, followed by a brief update on the status of the technology development at Lawrence Berkeley National Laboratory. We present a roadmap for the next decade to develop 20 T-class REBCO accelerator magnets as an enabling instrument for future energy-frontier accelerator complex.

In the perspective of this article, the emergence of materials and systems for magneto‐mechanical actuation in the field of mechanobiology is presented, and their potential to promote and advance biomedical research is discussed. These materials, ranging from single particles to compliant 2D substrates to 3D scaffolds, enable mechanical modulation of cells in a remote, dynamic, and reversible fashion. These features represent a major advance enabling researchers to reproduce time‐evolving physiological and pathological processes in vitro and transmit mechanical forces and deformations to activate cellular responses or promote directed cell migration. As smart in vitro platforms, magneto‐responsive systems may accelerate the discovery of mechanically mediated cellular mechanisms as therapeutic targets. In addition, the low magnetic susceptibility of biological tissues may facilitate the translation of in vitro approaches to in vivo settings, opening new routes for biomedical applications.
