A Cryogen-Free Miniature Dilution Refrigerator for Low-Temperature Detector Applications


We describe a miniature dilution refrigerator, suitable for many detector applications at temperatures down to 50 mK. Unlike conventional systems, the 3He gas is recycled internally which eliminates the need for any room-temperature pumps and gas handling system. No fine capillaries, moving parts or cooled O-rings are required which makes the system mechanically very reliable and minimizes the risk of developing blockages or cryogenic leaks during thermal cycles. We have integrated our dilution refrigerator with a pulse-tube cooler to create a cryogen-free, push button system which is now being used for TES detector developments. Temperatures below 50 mK and a cooling power of several micro-Watt at 100 mK is available for more than 15 hours at the time, with a re-cycle period of about 4 hours.
