Cryoprobe using closed gas loop for nuclear magnetic resonance apparatus
Abstract:
Provided is a cryoprobe using a closed gas loop for a nuclear magnetic resonance apparatus, including: superconducting magnets providing a magnetic field; a rotor rotatably disposed between the superconducting magnets in the state of a sample being put therein, the rotor being rotated by a driving gas; a coil configured to generate a nuclear magnetic resonance spectrum according to a resonance phenomenon of the sample by applying a radio frequency to the rotor; and a gas loop configured to cool the driving gas in a cryogenic condition while circulating it in a closed-loop condition and to supply the driving gas to the rotor, wherein the gas loop supplies the driving gas to the rotor while cooling it in a cryogenic condition, thereby rotating the rotor.
