摘要
A practical cryogenic probehead for NMR microscopy is described. The superconducting coil is composed of a YBa2Cu3O7 layer on a LaAlO3 substrate. The probehead consists of a continuous flow cryostate with a room temperature bore for the sample. For better performance the sample can be positioned in the center of the coil. To evaluate the gain in sensitivity, spin-echo images are presented which compare the YBa2Cu3O7 (YBCO) resonator to a room temperature and a cryogenic Cu resonator. These results are corroborated through theoretical calculations. To estimate the potential of superconducting coils for NMR microscopy we have made a theoretical comparison of an YBCO resonator with a microscopic solenoid with three winding.
