TL;DR: The new NI winding offers HTS coils enhanced performance in three key parameters: overall current density; thermal stability; and mechanical integrity.

TL;DR: A copper oxide high-temperature superconductor magnet generates a direct-current magnetic field of 45.5 tesla—the highest value reported so far—using a design that enables operation at high current densities, validates predictions11 for high-field copper oxide super Conductor magnets by achieving a field twice as high as those generated by low-tem temperature superconducting magnets.

TL;DR: Experimental and analytical studies on the characteristic resistance of NI (no-insulation) ReBCO pancake coils, which are used in an equivalent circuit model to characterize 'radial as well as spiral' current paths within the NI coils, identified turn-to-turn contact resistance as a major source of the characteristic Resistance of an NI coil.

TL;DR: A 26 T 35 mm winding diameter all-GdBa2Cu3O (GdBCO) magnet was designed by the MIT Francis Bitter Magnet Laboratory, and constructed and tested by the SuNAM Co., Ltd as discussed by the authors.

TL;DR: The main goal of this paper is to clarify transient electromagnetic and thermal behaviors and mechanism of the high thermal stability in an NI REBCO coil, and a partial element equivalent circuit (PEEC) model is proposed for the numerical simulation, which considers a local electrical contact resistance between turns.
