Zusammenfassung:A cooling system 10, an apparatus for producing hyperpolarized samples, where the apparatus includes the cooling system, and a method for assembling and using the cooling system are disclosed. The cooling system 10 includes a cryogenic chamber 16, a cooling plate 36, a sample sleeve 14, a thermal switch 42, and an interposer 70. Also, the cryogenic chamber 16 includes a cryogenic fluid 32 and the cooling plate 36 is disposed in the cryogenic chamber 16, in contact with the cryogenic fluid 32. Further, the sample sleeve 14 is configured to receive a sample. The sample sleeve 14 is at least partially inserted in the cryogenic chamber 16. The thermal switch 42 is disposed between the cooling plate 36 and the sample sleeve 14. Moreover, the interposer 70 is disposed between at least one of (i) the thermal switch 42 and the cooling plate 36 and (ii) the thermal switch 42 and the sample sleeve 14. The interposer 70 includes a gallium indium tin alloy.
