摘要：

Presents a detailed comparison of different existing cryostats for a range going from liquid nitrogen to room temperature. None of these was really adapted for continuous operation between these two temperatures in a large volume with a good stability. The new apparatus is a double cryostat adapted for this range. The output cryostat is cooled by the evaporation of a servo-controlled flow of liquid nitrogen and the inner cryostat is maintained by a slightly higher temperature by a servo-controlled electric heater. This device gives a stability of 0.001K with a temperature difference of 0.01K in a volume of a few litres.
