Considering that in a magnetic resonance system, if the detection coil contributes dominantly to the system noise, the performance of the whole system can certainly be improved by switching to a detection coil made of a high-temperature superconductor, and using YBa2Cu3O7 thinfilms on 25 × 25 mm2 LaAIO3 substrates, we have prepared two kinds of detection coils: single-coil and two-coil. Encouragingly, their quality factors are measured to be Q > 2500 for two-coil (at 22.566MHz and 77K) and Q > 5500 for single-coil (at 92.3MHz and 77K),respectively. Here, we describe the details of the design, fabrication and testing of the coils.
