抄録
Features of a cryostat under construction in Tokyo and intended for fast operation at ultra low temperatures will be described. Highly conductive copper is used for both of the following reasons. 1. To achieve the ultimately low temperature and 2. To reduce the entropy loss while precooling of the copper nuclear demagnetization stage by a PrNi5 nuclear demagnetization refrigerator, which achieves continuous cooling by means of two stages which are demagnetized alternately.
