Résumé

The function of the cryogenic ground support equipment (CGSE) system is to cool down the AMS-02 magnet and to fill the magnetic Dewar of AMS-02 detector with He II. The controlled cooling system of 300-80 K is an important subsystem in CGSE system. Its main function is to cool down the magnet of AMS-02 from 300 to near 80 K. The magnet obviously suffers heat expansion and cold shrink when it is cooled from 300 to 80 K. In addition, the high-pure medium is to be used in the system. Therefore, the controlled cooling system of 300-80 K is designed in detail. The cooling process should be uniform and the maximal temperature difference during the cooling process is no more than 50 K. These requirements can be attained by the adjustable cryostat. The structures and characteristics of the main components and the composing of the system are also presented. Heat exchanger 1 is a cryogenic gas heat exchanger which can eliminate stress automatically and prevent its medium from being polluted. Heat exchanger 3 is a cryogenic boiling heat exchanger which can automatically complement liquid and make the liquid level steady.
