Abstract: | A He3-He4 dilution refrigerator has been constructed which circulates He3 by using two alternately operating adsorption pumps which are in the same cryostat as the dilution refrigerator. The scheme described here organised the low temperature circulation cycle such that the construction and cryostat communications were essentially simplified, the dimensions of the arrangement were decreased which resulted in a circulation velocity of 10?4 mole s?1, which was sufficient to obtain a temperature in the order of 10 mK. |
