✦ Synopsis

A new type of mixing chamber is described with which any dilution refrigerator, capable of reaching 30 mK continuously, can now attain temperatures below 3 mK when operating in the singl~cycle mode.

In a preliminary experiment this mixing chamber used in a dilution refrigerator with an additional superfluid He 4 circulation of 2 x 10 -3 moles s-1 reached a temperature of 4 mK continuously.
