摘要： A method and apparatus for filling superconductive magnets is disclosed by using gaseous helium to control the flow of liquefied helium from a container to a magnet. By measuring the pressure of the gaseous helium in the container of liquefied helium, it can be determined when to stop the flow of liquefied helium. This can reduce quenches and helium losses which can occur during the transfer of liquid helium from the dewar to the superconductive magnet.

摘要： A method for providing cooling to the superconducting coils of a magnet with cryogenic helium gas at a helium production facility is disclosed. The cryogenic helium gas is fed to the magnet where the helium provides cooling. Cryogenic liquid helium provides additional cooling and fills the helium reservoir. Methods are also provided for recovering vaporized helium from the filling of a magnet and when the magnet is undergoing energization at the helium production facility.

摘要： The invention relates to a superconductive magnetic coil. The magnetic coil is located in a cryostat for cooling purposes which is filled only up to a certain fill level with liquid helium. A helium gas phase having a temperature stratification, in which, for example, temperatures are present that can lead to a collapse of the superconductivity, forms over said helium accumulation. The magnetic coil is therefore subdivided into at least two partial regions having differing heat transfer between the coil and the surrounding medium. In a first partial region of the coil, in the surroundings of which a sufficiently low temperature for cooling is present, the heat transfer is high, while the magnetic coil in a second partial region, in the surroundings of which the temperature of the cooling medium is above a critical value, exhibits heat insulation. Consequently, no heat is exchanged between the coil and the surroundings in the second partial region, while cooling of the coil takes place in the first partial region.
