Abstract
A cryostat for a superconducting magnet system is provided. The cryostat may include an outer vessel and an inner vessel suspended within the outer vessel. A space may be defined by the outer vessel and the inner vessel. The cryostat may include multiple first support elements and one or more second support elements. The strength of the first supporting element may be larger than that of the second support elements. The inner vessel and the outer vessel may be connected by two opposite ends of a first support element and two opposite ends of a second support element, respectively. The number of the first support elements in the lower part of the space is different from the number of the first support elements in the upper part of the space.
