How much liquid helium is needed for a magnetic **** vibration

2000 liters. Nuclear magnetic *** vibration, also known as nuclear magnetic *** vibration imaging technology, each device needs 2000 liters of liquid nitrogen as a cooling medium, the lack of liquid nitrogen content will lead to equipment loss of super, resulting in machine destruction. With the emergence of 5T, 7T and other higher field strength magnetic *** vibration, liquid helium demand will only increase.
