Document Type and Number:
WIPO Patent Application WO/2013/094325
Kind Code:
A1
Abstract:
The invention relates to a liquid nitrogen cooling sensor device container and liquid nitrogen cooling sensor device, and effectively reduces low-frequency noise while maintaining the ease with which a probe can be inserted in and removed from liquid nitrogen. Said invention comprises: a thermally insulated liquid nitrogen holding container that holds liquid nitrogen; a sensor affixing member to a tip portion of which is attached a sensor that operates by means of the temperature of the liquid nitrogen; and an affixing buffer member for affixing the sensor affixing member to the thermally insulated liquid nitrogen holding container. A member having a buffer action in the liquid nitrogen is used as the affixing buffer member.
