Compact dilution refrigerator for sensor cooling.

Number: pap. n. 053

Author(s) : SCHNEIDER M., ARNDT J., GIESEL J., et al.


A special dilution refrigerator with pulse-tube precooling has been designed, constructed and tested with the purpose of cooling (terahertz) radiation sensors or cryogenic electronics to very low temperatures. The whole setup features tilt independence, angles of up to 45° from its upright position are possible without significant loss of cooling power due to specially designed key components as for example the mixing chamber. Two independent but thermally coupled 3He circulations permit a high level of temperature stability. The experimental optimisation includes for example an improved design of the radiation shields. Furthermore, different types of heat switches have been investigated in order to find the best refrigerator performance.
