Cryostat and magnetism measurement apparatus using the cryostat

摘要

Coolant (3) whose boiling point is higher than the temperature of cooled SQUID elements (2) as cooled objects is poured into an inner container (37) for containing SQUID elements. The SQUID elements (2) are soaked in the coolant (3). Before the inner container (37) for containing SQUID elements is used, the coolant (3) is cooled and solidified by a refrigerator (7).
