Paper Abstract

Low-resistance probe coils offer improved low-noise detection of rf magnetic fields in low- signal-level magnetic-resonance imaging and spectroscopy applications. Coils are presented that have been designed for: (1) low-field MRI machines; (2) NMR microscopes; and (3) NMR spectrometers. Quality factors (Q) exceeding 104 have been achieved for all three applications by the use of thin films of the high-temperature superconductor YBa2Cu3O7-(delta) . The first ever coil utilizing multilevel superconducting films is presented. Progress in the application of these coils to high-performance instruments is reviewed.
