Author(s) : BOGOJAVLENSKIJ I. V.

Type of article: Article

Summary

TEMPERATURES LOWER THAN 1.3 K ARE PRODUCED BY MEANS OF PUMPING OUT VAPOUR ABOVE LIQUID HELIUM 3 WITH AN ADSORPTION PUMP LOCATED IN THE DEVICE ITSELF. A MINIMUM TEMPERATURE IS HELD DURING 140 H. THE ESSENTIAL TIME FOR THE CRYOSTAT START IS ABOUT 10 H. THE CRYOSTAT WAS USED FOR THE MEASUREMENT OF TEMPERATURE DEPENDENCE OF THE BOSE-CONDENSATE DENSITY IN HELIUM 4.
