A method for ensuring minimal thermal transfer and temperature gradient in a high vacuum cryogenic chamber has inner, intermediate and outer housings

摘要

The outer hosing (1) contains the intermediate housing (2) having foil radiation insulation (3) and support legs (4) which houses the cryogenic chamber (6) having a high mass (8) and support legs (7). The temperature is reduced by cooling units (12) and a hollow space (13) containing refrigerant.
