摘要：

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 He-3-B down to temperatures of similar to 280 mu K in a single-walled experimental cell. The apparatus is currently used to study the magnetic relaxation processes in superfluid He-3. (C) 1997 Elsevier Science Ltd.
