✦ Synopsis

A nuclear demagnetization

refrigerator with diffusion-welded copper nuclear stage has been constructed and successfully operated. The stage consists of 80 mol of copper and is capable, starting from an initial magnetic field of 6.4 T, of cooling the superfluid 3He-B down to temperatures of -280 PK in a single-wailed experimental cell. The apparatus is currently used to study the magnetic relaxation processes in superfluid 3He.

Two-stage nuclear demagnetization has been performed using PrCu6 and Cu as coolants. The Cu nuclear stage reached temperatures as low as 10 izK with a rate of temperature rise of less than a few IxK/h. The corresponding conduction electron temperature is estimated to be less than 50 I~K. A nuclear o
