Abstract

The invention relates to a cooling method of a low-temperature superconducting magnet and a system thereof. The characterized is that before cooling the low-temperature superconducting magnet by liquid helium, a superconducting magnet coil is precooled by using liquid nitrogen, and the liquid nitrogen is completely discharged by using the helium pressure method; and then the superconducting magnet coil cooled to the temperature of the liquid nitrogen is cooled to the temperature of the liquid helium by using the liquid helium, thus effectively reducing the consumption of the liquid helium with high price and scarce resources in the process of cooling the existing low-temperature superconducting magnet.
