Abstract

Low noise detectors offer improved performance in low-signal-level nuclear-magnetic-resonance (NMR) spectroscopy and imaging (MRI) applications. High temperature superconducting coils, fabricated with YBa2Cu3O7-δ thin films, were developed for high resolution NMR spectroscopy. Quality factors exceeding 104 have been achieved in a 9.4 T magnet. Current handling and magnetization of the coils approach the desired requirements. High resolution NMR spectra have been successfully obtained with these coils. A signal-to-noise ratio improvement over conventional technology of more than a factor of 4 was realized.
