NMR MAGNET SYSTEM WITH SUPERCONDUCTING COIL IN A HELIUM BATH |
摘要 |
In an NMR magnet system for generating a highly homogeneous magnetic field of high field strength, with at least one superconducting magnet coil which is arranged in a first chamber of a cryostat in supercooled liquid helium at a temperature of less than 4.2K, with the cryostat having at least one further chamber containing liquid helium that is essentially at atmospheric pressure with a temperature of approximately 4.2K, the first chamber is connected to the further chamber in such a way that the supercooled liquid helium located in the first chamber is also essentially at atmospheric pressure. A refrigerator with which the liquid helium can be cooled to a temperature T<<4.2K, especially to T APPROX 1.8-2.3K, is provided in the first chamber.
