A coil without turn-to-turn insulation, called a no-insulation (NI) coil has been developed. The NI winding technique has been reported to be a promising method of quench protection. In order to apply the NI winding technique to a conduction-cooled R

When superconducting magnets are operated in a conduction-cooling system, if a malfunction of the cryocooler or an abnormality in the heat transfer path occurs, the temperature of the coil increases. In most cases, the operating temperature limit is

Since REBa 2 Cu 3 O 7-δ (REBCO) coils have high thermal stability, the possibility of quenching is considerably lower than low-temperature-superconducting coils. However, if thermal runaway is observed in a conduction-cooled system, a REBCO coil wil

In order to use a coil wound with REBCO-coated conductor in a conduction cooling configuration, ac loss of the coil should be quantitatively predicted and designed under the operating conditions, for example during charging-up and -down, or shutdown

In recent years, high-field magnets wound with REBCO tape and their applications to magnetic resonance imaging (MRI) have undergone considerable research and development. MRI coil systems require a highly accurate field in the imaging space. However,

Superconducting magnets for magnetic resonance imaging systems require homogeneous, stable magnetic fields. The homogeneity of the magnetic field is highly dependent on the coils shape and positions. Furthermore, in REBa2 Cu3O7−δ (REBCO) magnets,

We started developing REBa 2 Cu 3 O 7-δ (REBCO) magnets for ultrahigh-field magnetic resonance imaging (MRI) systems in 2013. Our final targets are 9.4 T MRI systems for whole-body and brain imaging. In this paper, a conduction-cooled 1.5 T REBCO MR
