We report on the development and characterization of superconducting damascene tantalum nitride (TaN) nanowires, 100 nm–3 μm wide, with TaN thicknesses varying from 5 to 35 nm, using 193-nm optical lithography and chemical mechanical planarization

We report on the development of a chemical mechanical planarization (CMP) process for thick damascene Ta structures with pattern feature sizes down to 100 nm. This CMP process is the core of the fabrication sequence for scalable superconducting integ

A prototype persistent current switch is developed for an actively shielded whole-body 1.5 T MRI magnet having an operating current of ∼500 A. The switch is developed using a six-strand CuNi-NbTi conductor. The total length of the conductor used in

A whole-body 1.5 T superconducting MRI magnet is operated in 4.2 K inside a zero-boil-off helium cryogenic vessel, i.e., cryostat. The cryostat has horizontal bore of 850 mm used as the patient bore. The cryostat houses the 1.5 T superconducting magn
