PROCESS AND DEVICE FOR CREATING AN EVACUATED, DEEP-TEMPERATURE ENVIRONMENT FOR A SAMPLE

摘要

A device for creating an evacuated, deep-temperature environment for a sample comprises a cooling chamber (10) for receiving a coolant (12), and a sample chamber (14) which can be evacuated and is provided with a sample holder (16) for fastening the sample in the sample chamber, as well as a cooling section (18) which is solidly connected to the sample holder, is designed for direct contact with the coolant and forms part of the outer boundary (20, 24, 26, 28, 30) of the sample chamber. In the evacuated state, the sample chamber can be moved relative to the cooling chamber between a first position in which the cooling section is not in contact with the coolant, and a second position in which the cooling section is in direct contact with the coolant. The sample chamber (14) comprises a bellows arrangement (26, 28), as well as a top endpiece (30) and a bottom endpiece (30) interconnected in a vacuum-tight manner by the bellows arrangement.
