Abstract
Cryostat systems for magnetic resonance imaging system are provided. The cryostat system may include a tank containing a cavity to accommodate a cooling medium and a superconducting coil. The system may also include a cold head assembly configured to cool the cooling medium to maintain the superconducting coil in a superconducting state. The cold head assembly may be mounted on the tank. The cold assembly may include at least a first cold head and a second cold head. The second cold head may include a taper shape with a first end surface close to the first cold head and a second end surface away from the first cold head. A diameter of the first circular end is greater than a diameter of the second circular end.
