  • Patent number: 9696391
    Abstract: A precision high-speed shuttle device for transporting samples between different positions of a superconducting magnet with different magnetic field strength is provided. The sample equilibrated at the center of the magnet, where the magnetic field is the highest and homogeneous, is shuttled to a higher position above, where the fringe field is lower, for a defined period of time and shuttled back to the center for detection. By shuttling the sample to different positions in the magnet in different experiments one can obtain a field-dependent profile of particular physical parameters. The position and timing of the sample are precisely under the experimental controlled. In this way various magnetic field-dependent nuclear magnetic resonance (NMR) experiments can be conducted in a single high-field NMR spectrometer.
