等の性能に悪影響を及ぼす。Cryogenic equipment can be operated for long periods of time by cooling with a refrigerator. Refrigerators for cryogenic temperatures include expansion engines and Gibbard-McMahon refrigeration:? The gas is pre-cooled by the auxiliary cooling device, and the dead gas is further cooled by a heat exchanger and then expanded by Joule-Thomson. Small auxiliary cooling devices generally have a reciprocating groove,
The vibrations generated thereby have an adverse effect on the performance of the cryogenic apparatus, such as magnetic field homogeneity.
