Abstract
A persistent-mode magnet, assembled from superconducting annuli, provides a micro coil NMR, in which compactness and manufacturability are provided for a variety of applications. An annular magnet for micro NMR can include a YBCO-annulus Helmholtz coil, for example, that can energized by a magnet system and then transported for use at a second location with an operating system.
Claims48
A magnetic resonance system comprising:
- a magnet system having a plurality of superconducting layers;
- a shim element;
- a cooling system that cools the plurality of superconductive layers to an operating temperature;
- and
- an energization system that energizes the magnet system.
A method of using a magnet system for magnetic resonance spectroscopy comprising:
- energizing a superconducting magnet layers to form a magnetic field;
- subsequently connecting the magnet to a magnetic resonance operating system;
- and
- obtaining a magnetic resonance spectrum of a material with the operating system.
